Hi Andrea,
I think the first part is fine when approved, but the 2nd part is problematic
like Szabolcs
already pointed out. We can't just change the ABI or semantics, and these
builtins are critical
for GLIBC performance. We would first need to change GLIBC back to using inline
assembler
so it

Hi all,
second and last patch of the two reworking FPCR and FPSR builtins.
This rework __builtin_aarch64_set_fpcr (unsigned) and
__builtin_aarch64_set_fpsr (unsigned) to emit a read-modify-sequences
as:
mrs x1, fpsr
bfi x1, x0, 0, 32
msr fpsr, x1
