Did you attach the correct file? I get

‘__builtin_c23_va_start’; did you mean ‘__builtin_ms_va_start’?

If it immediately reboots (and you didn't use panic=XXX to reboot quickly) then
it might be a triple fault. These are unfortunately harder to debug because
they don't produce any console output in a native set

--- Comment #8 from Andi Kleen ---
Classical "make photo of panic" screen method should be enough.
The critical part is the Code: line that shows the bad instruction, and the
name of the function.

It's quite difficult to express the rules for tail calls for all targets in
dejagnu effective rules.
Currently we're a bit too aggressive for excluding on Power, but nobody has the
energy to reopen it again,

The problem seems to be that the call BB has an extra fallthrough edge to the
basic block containing the return. Perhaps it should just have an EXIT edge or
not split the RETURN? (not sure if that is legal in

The C test case needs to use constexpr too.
#define DATA_SIZE 1024
static constexpr int TO_DATA_INDEX[DATA_SIZE] = {};
bool foo(int* data, unsigned char first_idx)
{
int second_idx = TO_DATA_INDEX[first_idx]

--- Comment #9 from Andi Kleen ---
With constexpr you are guaranteed an visible initializer. const would
potentially require messing with IPA and might impossible.

--- Comment #7 from Andi Kleen ---
We need a validator for x86 assembler length indications in the x86 machine
descriptions, then it could be easily enabled.
This will require patching gas at least for test suite runs.

After some digging into the code: libcpp already keeps track of how many tokens
get expanded in a global. This is even accessible for through linemap's
statistics dumped on -fmem-report, but only as a averaged

It's too late to fix gcc 15, you'll just have to release an update. Sorry.

Something like this untested patch would likely also fix the test case:

For the gcc 15 release we could just drop the clang:: support, so it becomes
opt-in? (have to use gnu::musttail)

I already had that commit in my tree, since it was already on trunk.
Or did you think of something different?

I applied Alex's patches, but had to resolve one conflict. Unfortunately made
no difference in the test results.

Yes the multiple passes are a problem. They also do redundant work I believe.
But it would be easier to just check opt_tailcalls I think instead of adding a
new variable.

It doesn't really help for the PR119387 test case, perhaps not surprising
because it optimizes freeing not allocation:
