Bug ID: 127955
Summary: Broken strsignal, strbk fallbacks
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: build
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
Both of these are wrong fallbacks for when we can't find strsignal or sbrk:
gcc/system.h:extern const char *strsignal (int);
gcc/system.h:511:extern void *sbrk (int);
strsignal's return type isn't const. We define it in libiberty with the correct
return type anyway for the actual implementation: r0-88033-g6819ba36b3805c.
As for sbrk, it takes a ptrdiff_t, not an int.
I'll fix both of these though we would expect these fallbacks to not really
ever be needed. I only saw them because of an unrelated issue when finding GMP
(PR127954).
