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

Fix link order in cosmopolitan.a It turned out that the linker was doing the wrong with the amalgamation library concerning weak stubs. A regression test has been added and new binaries have been uploaded to https://justine.lol/cosmopolitan/ Ideally this should be fixed by building a tool that turns multiple .a files into a single .a file with deduplication. As a workaround for now the cosmopolitan.a build is restructured to not include LIBC_STUBS which meant technical debt needed to be paid off where non-stub interfaces were moved to LIBC_INTRIN and LIBC_NEXGEN32E. Thank @PerfectProductions in #31 for the report!

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 chibicc This program popped up on Hacker News recently. It's the only modern compiler I've ever seen that doesn't have dependencies and is easily modified. So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries.

Make build hermetic without shell scripts - Fix some minor issues in ar.com - Have execve() look for `ape` command - Rewrite NT paths using /c/ rather /??/c:/ - Replace broken GCC symlinks with .sym files - Rewrite $PATH environment variables on startup - Make $(APE_NO_MODIFY_SELF) the default bootloader - Add all build command dependencies to build/bootstrap - Get the repository mostly building from source on non-Linux

Fold conv package into fmt Both packages had nearly identical dependency requirements, so merging them should help reduce the complexity of the build graph.

Fix vfprintf and derived functions not handling write errors (#798) The C standard states: > The fprintf function returns the number of characters transmitted, > or a negative value if an output or encoding error occurred or if > the implementation does not support a specified width length > modifier. - C Standard, 7.23.6.1.15. The fprintf function However, cosmopolitan fails to return a negative value in the case of an output error, meaning that a program such as: #include <stdio.h> int main() { FILE *fp = fopen("/dev/full", "w"); setbuf(fp, NULL); printf("fprintf: %d\n", fprintf(fp, "test\n")); printf("fflush: %d\n", fflush(fp)); } will, under cosmopolitan, print that no error occured in either of the calls to fprintf and fflush. This patch fixes this, along with the associated GitHub issue, https://github.com/jart/cosmopolitan/issues/784
