AArch64: Deprecate -mabi=ilp32
ILP32 was originally intended to make porting to AArch64 easier. Support
was
never merged in the Linux kernel or GLIBC, so it has been unsupported for
many
years. There isn't a benefit in keeping unsupported features forever, so
deprecate it now (and it could be removed in a future release).
gcc:
* config/aarch64/aarch64.cc (aarch64_override_options): Add warning.
* doc/invoke.texi: Document -mabi=ilp32 as deprecated.
gcc/testsuite:
* gcc.target/aarch64/inline-mem-set-pr112804.c: Add -Wno-deprecated.
* gcc.target/aarch64/pr100518.c: Likewise.
* gcc.target/aarch64/pr113114.c: Likewise.
* gcc.target/aarch64/pr80295.c: Likewise.
* gcc.target/aarch64/pr94201.c: Likewise.
* gcc.target/aarch64/pr94577.c: Likewise.
* gcc.target/aarch64/sve/pr108603.c: Likewise.
