Bug ID: 115512
Summary: _Float32 overloads in cmath cause ICE for default AVR
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: dv at vollmann dot ch
Target Milestone: ---
Target: avr
As reported in <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115511>, g++
produces an ICE for calling functions with _Float32 for which both float and
double overloads exist.
I got it for __hypot3, but there are probably several others.
I'm wondering if cmath should provide overloads for _Float32 at all if double
is 32 bits.
The problem can be reproduced with a single line source:
#include <cmath>
avr-g++ -std=gnu++23 -o cmath-only.o -c cmath-only.cc

I agree. I didn't know about _Float32 and thought it's just a typedef. But as a real type providing these overloads is fine. ^ permalink raw reply [flat|nested] 5+ messages in thread

I've now built a libstdc++ with your fix and cmath compiles fine :-) So this indeed is a non-bug. Thanks! ^ permalink raw reply [flat|nested] 5+ messages in thread
