Conversation
- Added wut_rules and wut/rpx/rpl.specs to share/ - Replaced wut's CMake-based buildsystem with a standard Makefile - Conflated all wut libraries into a single libwut.a library - wut's old buildsystems (CMake & plain make) are broken as a result, this will be fixed in the future - Docs, tests and samples are not buildable either at the moment - wutcrt/wutnewlib: - RPX start function is __rpx_start, while RPL is __rpl_start - __init/fini_wut_* functions are no longer weak - __init_wut/__fini_wut are instead weak - Removed _exit implementation - exit syscall now points to _Exit instead of pointing to itself - wutstdc++: - Renamed .cc files to .cpp - Temporarily disabled, due to an issue that will be addressed shortly - wutdevoptab: - Fixed uninitialized variable warnings in __wut_fs_read/write
- Added (dummy) __init/fini_wut_malloc stubs called by wutcrt in order to ensure that wutmalloc gets linked in - malloc/realloc/calloc now properly set errno to ENOMEM during failure - realloc no longer fails if ptr==NULL (in this case it works like a regular malloc) - realloc no longer does an out of bounds copy if the new size is smaller than the old size - free(NULL) is now supported as per the C standard - Disabled sbrk/malloc-lock support code in wutnewlib because newlib's malloc is replaced with wutmalloc
I was getting issues with __volatile__ for unknown reason, so moving this to a dedicated file sidesteps the issue entirely and passes this straight to GAS.
This reverts commit 370eeb2. I didn't know what this did, sorry.
Who knows? not me. Seems to work okay without it

This made _start be an always undefined symbol, which kinda backdoors ld's existing system for determining entrypoints. This will be important in the next commit ;D
ld will now auto-link everything to __rpx_start and pull in the correct crt *unless* rpl.specs is given on the commandline
apparently cmake also has a CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES
