Support Linux binfmt_misc and APE loading on Apple The "no modify self" variant of Actually Portable Executable is now supported on all platforms. If you use `$(APE_NO_MODIFY_SELF)` then ld.bfd will embed a 4096 byte ELF binary and a 4096 byte Macho file which are installed on the fly to ${TMPDIR:-/tmp}, which enables us launch the executable, without needing to copy the whole executable To prevent it from copying a tiny executable to your temp directory you need to install the `ape` command (renamed from ape-loader), to a system path. For example: # FreeBSD / NetBSD / OpenBSD make -j8 o//ape/ape cp o//ape/ape /usr/bin/ape # Mac OS # make -j8 o//ape/ape.macho curl https://justine.lol/ape.macho >/usr/bin/ape chmod +x /usr/bin/ape On Linux you can get even more performance with the new binfmt_misc support which makes launching non-modifying APE binaries as fast as launching ELF executables. Running the following command: # Linux ape/apeinstall.sh Will copy APE loader to /usr/bin/ape and register with binfmt_misc Lastly, this change also fixes a really interesting race condition with OpenBSD thread joining. 2022-05-21 07:52:58 -07:00			`#ifndef COSMOPOLITAN_APE_LOADER_H_`

Write tests for new APE loader and fix bugs - Add FreeBSD-specific mmap() flags - Reduce size of the APE loader from 8kb to 4kb - Work towards fixing the Makefile build on WSL - Automate testing of APE no-modify-self behaviors - Make the ape.S shell script code cleaner and tinier - Improve the APE sanity check to test behavior better - Fixed issue with ShowCrashReports() sigaltstack() on BSDs - Delete symbols for S_MODE magnums which wasted compile time If you checked out yesterday's APE commit, please run: rm -f /usr/bin/ape o/tmp/ape /tmp/ape "${TMPDIR:-/tmp}/ape" Because this change fixes certain aspects of the new ABI. We don't have automated migrations for APE loader versions yet. Thanks! You can also download prebuilt binaries here: - https://justine.lol/ape.elf (Linux/FreeBSD/NetBSD/OpenBSD) - https://justine.lol/ape.macho (Apple) Install the appropriate one as `/usr/bin/ape`. 2022-05-22 04:51:02 -07:00			`#define APE_LOADER_BASE 0x200000`
