There are 3 *new* patches after RFC v2: Address report from Alviro: - Replace `asm` with `__asm__`. Address suggestions from David: - x86-64: Use appropriate register constraints if exist (Suggested by David). - i386: Use appropriate register constraints if exist. @@ Changelog: --- Link RFC v2: https://lore.kernel.org/lkml/20220322102115.186179-1-ammarfaizi2@gnuweeb.org/ RFC v2 -> v1: - Rebase, sync with Paul's tree. - Add new 3 patches [PATCH 03/11], [PATCH 04/11], [PATCH 05/11]. [PATCH 02/11] - Append Reviewed-by tag from Nick. - s/Removing/remove/ [PATCH 06/11] - Use the same pattern for syscall6, regardless using GCC or Clang (comment from David). - Use appropriate constraints for syscall6 instead of always using register variables (comment from David). [PATCH 09/11] - Round up the malloc() allocation to 4096 (comment from David). - Don't realloc() if we still have enough memory to contain the requested new size (comment from David). - Fix conflict with getenv() fix (after rebase). Link RFC v1: https://lore.kernel.org/lkml/20220320093750.159991-1-ammarfaizi2@gnuweeb.org/ RFC v1 -> RFC v2: - Add 2 new patches [PATCH 5/8] and [PATCH 7/8]. [PATCH 2/8] - Remove all `.global _start` for all build (GCC and Clang) instead of removing all `.weak _start` for clang build (Comment from Willy). [PATCH 3/8] - Fix %ebp saving method. Don't use redzone, i386 doesn't have a redzone (comment from David and Alviro). [PATCH 6/8] - Move container_of() and offsetof() macro to types.h with a separate patch (comment from Willy). [PATCH 8/8] - Update strdup and strndup implementation, use strlen and strnlen to get the string length first (comment from Willy and Alviro). - Fix the subject line prefix, it was "tools/include/string: ", it should be "tools/nolibc/string: ". - Update the commit message.
