src/external/gpl3/gcc/dist/gcc/config/i386: i386.c netbsd-elf.h
Fix GCC to correctly implement the i386 psABI on NetBSD.
This consists of two parts:
- for NetBSD/i386 and NetBSD/AMD64 with -m32, use a default stack
alignment of 23bit as specified by the ABI
- ensure that double and long long variables on the stack are by default
only aligned to 32bit, if there is nothing else in the function
needing a larger stack alignment
The combination ensures that SSE variables on the stack trigger the
realignment logic, but just using double or long long doesn't.
