In the Linux kernel, u64/s64 are [un]signed long long, not [un]signed
long. This means that when the `arm_neon.h' header is used by the
kernel, any use of the `uint64_t' / `in64_t' types needs to be
correctly cast to the correct `__builtin_aarch64_simd_di' /

Following the instruction cost fix, we are generating

With loongarch-def.cc switched from C to C++, we can include rtl.h for

THis is a non-functional change for now, but it will make the code more

This patch try to introduce the rwlock and split the read/write to
unit_root tree and unit_cache with rwlock instead of the mutex to
increase CPU efficiency. In the get_gfc_unit function, the percentage
to step into the insert_unit function is around 30%, in most instances,

Hi!
This testcase got fixed with
r14-6132-g50f2a3370d177f8fe9bea0461feb710523e048a2 .
I'm just adding a testcase so that it doesn't reappear.
Tested on x86_64-linux, with -m32/-m64, current trunk as well as r14-6131
where it ICEd with -m32, committed to trunk as obvious.

It's more reasonable to fix it in vec_perm_const instead of fix it in
middle-end.

Hi,
we currently try to recognize various forms of stepped (const_vector)
sequence variants in expand_const_vector. Because of complications with
canonicalization and encoding it is easier to identify such patterns
in expand_vec_perm_const_1 already where perm.series_p () is available.

Hi!
This function is never called when param_l1_cache_line_size is 0,
but it uses int and unsigned int variables to hold alignment in
bits, so for large param_l1_cache_line_size it is zero and e.g.
DECL_ALIGN () % param_align_bits can divide by zero.
Looking at the code, the function uses tree_fit
