When -fmultiflags option support was added in r13-3693-g6b1a2474f9e422,
it accidently allowed -fno-multiflags which then would pass on to cc1.
This fixes that oversight.
Committed as obvious after bootstrap/test on x86_64-linux-gnu.

Hi Jeff,
Is there any suggestion(s) for how to fix this ICE in the reasonable approach?
Thanks a lot.

Kito told me that Greg will help to add that parts. Let's wait the comments
from Kito.
Personally prefer a separated PATCH to cover that instead of appending here.

The behavior of non-zero unused bits in xvpermi.q instruction's
third operand is undefined on LoongArch, according to our
discussion (https://github.com/llvm/llvm-project/pull/83540),
we think that keeping original insn operand as unmodified
state is better solution.

Previously, calling erase(key) on both std::map and std::set
would execute that same code that std::multi{map,set} would.
However, doing that is unnecessary because std::{map,set}
guarantee that all elements are unique.
It is reasonable to expect that erase(key) is equivalent

This ICE started with the fairly complicated r13-765. We crash in
gimplify_var_or_parm_decl because a stray VAR_DECL leaked there.
The problem is ultimately that potential_prvalue_result_of wasn't

Dear all,
the attached patch fixes an ICE-on-valid code when assigning

When internal_get_tmp_var fails to gimplify the value the temporary
SSA name is supposed to be initialized with we can leak SSA names
with a NULL SSA_NAME_DEF_STMT into the IL. That's bad, so recover
from this by instead returning a decl in that case.

Should we perhaps
Using dummy procedures in a target region with 'defaultmap(none)' leads to:
Error: 'g' not specified in enclosing 'target'
and this cannot be fixed by using 'firstprivate' as non-pointer dummy routines
are rejected as "Error: Object 'g' is not a variable".
Fixed by doing the same for mapping

Ok.
They both come from an oversight of mine in the placement of the DIE created
for an enumeration type with reverse scalar storage order.
Tested on x86-64/Linux, both GCC and GDB, applied on mainline as obvious.

This patch removes some unnecessary definitions of target hook
functions according to the documentation of GCC.
gcc/ChangeLog:
* config/loongarch/loongarch-protos.h
(loongarch_cfun_has_cprestore_slot_p): Delete.
(loongarch_adjust_insn_length): Delete.
There's some ununsed/useless definition inside LoongArch target support
codes, these patches make a simple cleanup. Regression test passed.
Chenghui Pan (3):
LoongArch: Remove unused/useless definitions.
LoongArch: Change loongarch_expand_vec_cmp()'s return type from bool
to void.
These macros are completely same in definition, so we can keep the previous one
and
eliminate later one.
gcc/ChangeLog:
* config/loongarch/loongarch.cc (loongarch_hard_regno_mode_ok_uncached):
Combine UNITS_PER_FP_REG and UNITS_PER_FPREG macros.
This function is always return true at the end of function implementation,
so the return value is useless.
gcc/ChangeLog:
* config/loongarch/lasx.md: Remove checking of
loongarch_expand_vec_cmp()'s
return value.
* config/loongarch/loongarch-protos.h
