Hi!
This function would have UB if called with empty candidates vector
(accessing p[-1] where p is malloc (0) result).
As analyzed in the PR, we never call it with empty vector, so this just
adds an assertion to make it clear.

__builtin_unreachable and __ubsan_handle_builtin_unreachable don't

When -dx option is used (didn't know we have it and no idea what is it

Hi!
These tests fail on ia32, because we get -Wpsabi warnings.
Fixed by adding -Wno-psabi. The pr94920.C test still fails the
ABS_EXPR scan-tree-dump though, I think we'll need to add vect
options and use vect_int effective target or something similar.

{
T t;
return std::move (t); // warning \o/
}
However, the warning doesn't warn when what we are returning is a class
prvalue, that is, when std::move prevents t

This patch adds the additional options on RISC-V target.
"-fprefetch-loop-arrays" option needs enable prefetch instruction,
for RISC-V that contained in "zicbop" extension.
Use "-march" with "zicbop" will enable this feature.

The following patches add support for doing built-in function overloading
between the two 128-bit IEEE types (i.e. _Float182/__float128 using KFmode and

[PATCH 1/5] IEEE 128-bit built-in overload support.
This patch lays the ground work that future patches will use to add
builtin support (both normal and overloaded) for the case where long
double uses the IEEE 128-bit encoding.
This adds a new stanza (ieee128-hw-ld) for when we have IEEE 128-bit
