Get --ftrace working on aarch64 This change implements a new approach to function call logging, that's based on the GCC flag: -fpatchable-function-entry. Read the commentary in build/config.mk to learn how it works. 2023-06-06 06:35:31 +00:00			`.ftrace1`

Make improvements - Document redbean's argon2 module - Fix regressions in cthreads library - Make testlib work better with threads - Give the cthreads library lots of love - Remove some of the stdio assembly code - Implement getloadavg() across platforms - Code size optimizations for errnos, etc. - Only check for signals in main thread on Windows - Make errnos for dup2 / dup3 consistent with posix This change also fixes a bug in the argon2 module, where the NUL terminator was being included in the hash encoded ascii string. This shouldn't require any database migrations to folks who found this module and productionized it, since the argon2 library treats it as a c string. 2022-05-27 20:25:46 +00:00			`jmp __errfun`

Introduce native support for MacOS ARM64 There's a new program named ape/ape-m1.c which will be used to build an embeddable binary that can load ape and elf executables. The support is mostly working so far, but still chasing down ABI issues. 2023-05-19 02:05:08 +00:00			`ldrsw x0,[x1,#:lo12:ERESTART]`
