# Cosmopolitan Core Build Definitions

# DESCRIPTION
#
# Nearly all compiler flag tuning is done within this one file. Flags
# may be customized with environment variables. We also use this file
# to compute expensive values once per build.
#
# When tuning the variables below, please note they're interpreted in
# the strictest sense. For example, we don't pass CFLAGS to gcc if we

# to be succinct and informative at the cost of being less forgiving.

#
# Further note that link order is equally unforgiving in repositories
# of this scale. We approach that by over-specifying dependencies, in
# packages that're broken down usually on a per-directory basis. This
# is aided by the checkdeps and functional programming tools which in
# most cases should be able to deduce correct ordering automatically.
#
# Concerning our approach to flag tuning, most of it is non-essential
# and largely serves to turn features off. Particularly features that
# would otherwise lock us in to a particular platform or legal terms.
# Other flags will usually be the ones that provide us marginal gains
# in terms of performance and code size, but the world won't end when
# they aren't used. Flags that play a critical role in source working

Set LC_ALL=C in build config (#43) It's most likely the case (and SHOULD be the case) that C is the same locale as C.UTF-8. The only exception might be Python's gonzo unicode handling which whines when unicode is used without authorization, but that shouldn't be an issue since we don't need Python to build.

Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Rewrite .zip.o file linker This change takes an entirely new approach to the incremental linking of pkzip executables. The assets created by zipobj.com are now treated like debug data. After a .com.dbg is compiled, fixupobj.com should be run, so it can apply fixups to the offsets and move the zip directory to the end of the file. Since debug data doesn't get objcopy'd, a new tool has been introduced called zipcopy.com which should be run after objcopy whenever a .com file is created. This is all automated by the `cosmocc` toolchain which is rapidly becoming the new recommended approach. This change also introduces the new C23 checked arithmetic macros.

Prove that Makefile is fully defined The whole repository is now buildable with GNU Make Landlock sandboxing. This proves that no Makefile targets exist which touch files other than their declared prerequisites. In order to do this, we had to: 1. Stop code morphing GCC output in package.com and instead run a newly introduced FIXUPOBJ.COM command after GCC invocations. 2. Disable all the crumby Python unit tests that do things like create files in the current directory, or rename() files between folders. This ended up being a lot of tests, but most of them are still ok. 3. Introduce an .UNSANDBOXED variable to GNU Make to disable Landlock. We currently only do this for things like `make tags`. 4. This change deletes some GNU Make code that was preventing the execve() optimization from working. This means it should no longer be necessary in most cases for command invocations to be indirected through the cocmd interpreter. 5. Missing dependencies had to be declared in certain places, in cases where they couldn't be automatically determined by MKDEPS.COM 6. The libcxx header situation has finally been tamed. One of the things that makes this difficult is MKDEPS.COM only wants to consider the first 64kb of a file, in order to go fast. But libcxx likes to have #include lines buried after huge documentation. 7. An .UNVEIL variable has been introduced to GNU Make just in case we ever wish to explicitly specify additional things that need to be whitelisted which aren't strictly prerequisites. This works in a manner similar to the recently introduced .EXTRA_PREREQS feature. There's now a new build/bootstrap/make.com prebuilt binary available. It should no longer be possible to write invalid Makefile code.

Restore zip.com and .symtab files This change restores the .symtab symbol table files in our flagship programs (e.g. redbean.com, python.com) needed to show backtraces. This also rolls back earlier changes to zip.com w.r.t. temp directories since the right way to do it turned out to be the -b DIR flag. This change also improves the performance of zip.com. It turned out mmap() wasn't being used, because zip.com was assuming a 4096-byte granularity, but cosmo requires 65536.

Improve memory safety This commit makes numerous refinements to cosmopolitan memory handling. The default stack size has been reduced from 2mb to 128kb. A new macro is now provided so you can easily reconfigure the stack size to be any value you want. Work around the breaking change by adding to your main: STATIC_STACK_SIZE(0x00200000); // 2mb stack If you're not sure how much stack you need, then you can use: STATIC_YOINK("stack_usage_logging"); After which you can `sort -nr o/$MODE/stack.log`. Based on the unit test suite, nothing in the Cosmopolitan repository (except for Python) needs a stack size greater than 30kb. There are also new macros for detecting the size and address of the stack at runtime, e.g. GetStackAddr(). We also now support sigaltstack() so if you want to see nice looking crash reports whenever a stack overflow happens, you can put this in main(): ShowCrashReports(); Under `make MODE=dbg` and `make MODE=asan` the unit testing framework will now automatically print backtraces of memory allocations when things like memory leaks happen. Bugs are now fixed in ASAN global variable overrun detection. The memtrack and asan runtimes also handle edge cases now. The new tools helped to identify a few memory leaks, which are fixed by this change. This change should fix an issue reported in #288 with ARG_MAX limits. Fixing this doubled the performance of MKDEPS.COM and AR.COM yet again.

Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Prove that Makefile is fully defined The whole repository is now buildable with GNU Make Landlock sandboxing. This proves that no Makefile targets exist which touch files other than their declared prerequisites. In order to do this, we had to: 1. Stop code morphing GCC output in package.com and instead run a newly introduced FIXUPOBJ.COM command after GCC invocations. 2. Disable all the crumby Python unit tests that do things like create files in the current directory, or rename() files between folders. This ended up being a lot of tests, but most of them are still ok. 3. Introduce an .UNSANDBOXED variable to GNU Make to disable Landlock. We currently only do this for things like `make tags`. 4. This change deletes some GNU Make code that was preventing the execve() optimization from working. This means it should no longer be necessary in most cases for command invocations to be indirected through the cocmd interpreter. 5. Missing dependencies had to be declared in certain places, in cases where they couldn't be automatically determined by MKDEPS.COM 6. The libcxx header situation has finally been tamed. One of the things that makes this difficult is MKDEPS.COM only wants to consider the first 64kb of a file, in order to go fast. But libcxx likes to have #include lines buried after huge documentation. 7. An .UNVEIL variable has been introduced to GNU Make just in case we ever wish to explicitly specify additional things that need to be whitelisted which aren't strictly prerequisites. This works in a manner similar to the recently introduced .EXTRA_PREREQS feature. There's now a new build/bootstrap/make.com prebuilt binary available. It should no longer be possible to write invalid Makefile code.

Fully support OpenBSD 7.3 This change (1) upgrades to OpenBSD's newer kernel ABIs, and (2) modifies APE to have a read-only data segment. Doing this required creating APE Loader v1.1, which is backwards and forwards compatible with the previous version. If you've run the following commands in the past to install your APE Loader systemwide, then you need to run them again. Ad-hoc installations shouldn't be impacted. It's also recommended that APE binaries be remade after upgrading, since they embed old versions of the APE Loader. ape/apeuninstall.sh ape/apeinstall.sh This change does more than just fix OpenBSD. The new loader is smarter and more reliable. We're now able create much tinier ELF and Mach-O data structures than we could before. Both APE Loader and execvpe() will now normalize ambiguous argv[0] resolution the same way as the UNIX shell. Badness with TLS linkage has been solved. Fixes #826

Introduce post-linker that converts ELF to PE If you build a static ELF executable in `ld -q` mode (which leaves rela sections inside the binary) then you can run it through the elf2pe.com program afterwards, which will turn it into a PE executable. We have a new trick for defining WIN32 DLL imports in C without any assembly code. This also achieves the optimally tiny and perfect PE binary structure. We need this because it isn't possible to have a GNU ld linker script generate a PE file where the virtual pointer and the file pointer can drift apart. This post-linker can do that. One cool benefit is we can now use a smaller 512-byte alignment in the file, and an even bigger 64kb alignment for the segment virtual addresses, and the executable ends up being smaller. Another program introduced by this change is pecheck.com which can do extensive linting of PE static executables to help explain why Windows won't load it.

Rewrite .zip.o file linker This change takes an entirely new approach to the incremental linking of pkzip executables. The assets created by zipobj.com are now treated like debug data. After a .com.dbg is compiled, fixupobj.com should be run, so it can apply fixups to the offsets and move the zip directory to the end of the file. Since debug data doesn't get objcopy'd, a new tool has been introduced called zipcopy.com which should be run after objcopy whenever a .com file is created. This is all automated by the `cosmocc` toolchain which is rapidly becoming the new recommended approach. This change also introduces the new C23 checked arithmetic macros.

Make more improvements This change includes many bug fixes, for the NT polyfills, strings, memory, boot, and math libraries which were discovered by adding more tools for recreational programming, such as PC emulation. Lemon has also been vendored because it works so well at parsing languages.

Add The LISP Challenge This change introduces a 2.5kb program that's comes pretty close so far to bootstrapping John McCarthy's metacircular evaluator on bare metal.

Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html
