Ariadne Conill fb1d203677 everywhere: drop _GNU_SOURCE requirement 2021-03-09 00:25:13 -07:00
osy 5d66c194a7 x86_64: define reg names if not defined
_GNU_SOURCE can be defined without defining REG_X macros so it is not a
good indicator. (QEMU for example defines it in the build system.) x86
and x86_64 should have consistant looking defs.h so ifndef guards are
added to each REG_X definition.

osy f3e1b876c7 project: move freestanding include headers
This is needed because in libucontext.h we include "libucontext/bits.h".
We therefore need to have bits.h in somepath/libucontext/bits.h. In the
Makefile, somepath/freestanding/bits.h was copied to the right path but
in the meson build system, the include copy happens at the end.

Reorder registers in other x86_64 assembler files
This fixes the previous commit which changed the register order in
swapcontext only, which caused setcontext to subtly corrupt the stack.

Timo Teräs 790ed28aff fix x86_64 register order for swapcontext
rbp and rsi were reversed causing argument passing to fail since
rsi is used to pass 2nd argument.

fixes #9
