Fix target/93119 (aarch64): ICE with traditional TLS support on ILP32
The problem here was g:23b88fda665d2f995c was not a complete fix
for supporting tranditional TLS on ILP32.
So the problem here is a couple of things, first __tls_get_addr
call will return a C pointer value so we need to use ptr_mode
when we are creating the call. Then we need to convert
back that register to the correct mode, either zero extending
it or just creating a move instruction.
Also symbol_ref can either be in SImode or DImode. So we need to
allow both modes.
Built and tested on aarch64-linux-gnu with no regressions.
Also built a full toolchain (including glibc) defaulting to traditional
TLS that targets ilp32 and lp64.
ChangeLog:
PR target/93119
* config/aarch64/aarch64.md (tlsgd_small_<mode>): Have operand 0
as PTR mode. Have operand 1 as being modeless, it can be P mode.
(*tlsgd_small_<mode>): Likewise.
* config/aarch64/aarch64.c (aarch64_load_symref_appropriately)
<case SYMBOL_SMALL_TLSGD>: Call gen_tlsgd_small_* with a ptr_mode
register. Convert that register back to dest using convert_mode.
