gcc could infer that the check for f2 and the call to very_heavy are cold, and
move that little block to a .cold section, whether or not very_heavy is cold.

constexpr works but consteval does not.
Also I notice ICC rejects the consteval version but accepts the constexpr one.

Hi!
With -fstack-check=generic __builtin_alloca* can throw and the asan
instrumentation of this builtin wasn't prepared for that case.
The following patch fixes that by replacing the builtin with the
replacement builtin and emitting any further insns on the fallthru
edge.

Hi!
The following testcase ICEs, because AVX512F is enabled, AVX512VL is not,
and the cvtsd2ss insn has %xmm0-15 as output operand and %xmm16-31 as
input operand. For output operand %xmm16+ the splitter just gives up
in such case, but for such input it just emits vmovddup which requires
AVX512VL
