Hello,
I built a riscv64-rtems5 GCC (it uses gcc/config/riscv/t-elf-multilib). The
following multilibs are built:
riscv64-rtems5-gcc -print-multi-lib
.;
rv32i/ilp32;@march=rv32i@mabi=ilp32
rv32im/ilp32;@march=rv32im@mabi=ilp32
rv32iac/ilp32;@march=rv32iac@mabi=ilp32
rv32imac/ilp32;@march=rv32ima

Interaction with -mstackrealign on i386, where it is required for
system libraries to support applications which use the legacy ABI
without stack alignment if you compile with -msse2 or -march=x86-64

I brought this subject up earlier, and was told to suggest it again for gcc 9,
so I have attached the preliminary changes.
My studies have show that with generic x86-64 optimization it reduces binary
size with around 0.5%, and when optimizing for x64 targets with SSE4 or
better, it reduces bina
