Bug ID: 113915
Summary: [14 regression] glibc miscompiled for armv7a since
r14-4365-g0731889c026bfe
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: ramana at gcc dot gnu.org, wilco at gcc dot gnu.org
Target Milestone: ---
glibc seems to go from 30 failing innocent tests (*) to over 400 between gcc-13
and gcc-14. Bisected to r14-4365-g0731889c026bfe which fixed PR111235.
It's hard to know where to start with this. I'll try the usual bisection of
objects and then pragmas although I fear the (necessary) complexities of
glibc's build system may make my usual method tricky. We'll see...
I've bisected using glibc's posix/tst-getopt-cancel test as it had easy output
to grep for:
```
$ cat ./posix/tst-getopt-cancel.out
begin: no errors
Didn't expect signal from child: got `Segmentation fault'
```
(*) just from sandboxing stuff, they're normally not there and should be
unrelated given they happened w/ 13.
