Tested for cris-elf. Ok to commit?
-- >8 --
Looks like there's a failed assumption that
sizeof (union U { char u1[5]; int u2; float u3; }) == 8.
However, for "packed" targets like cris-elf, it's 5.
These two tests have always failed for cris-elf. I see from
https://gcc.gnu.org/pipermail/gcc-testresults/2023-February/777912.html
that they fail on pru-elf too, but I don't know if the cause
(and/or remedy) is the same.
IMHO this is preferred over the alternative; splitting up
that last line into two lines, like:
/* { dg-final { scan-tree-dump "temp4 = \
.DEFERRED_INIT \\(8, 2, \&\"temp4\"" "gimple" { target { ! default_packed } }
} } */
/* { dg-final { scan-tree-dump "temp4 = \
.DEFERRED_INIT \\(5, 2, \&\"temp4\"" "gimple" { target default_packed } } } */
gcc/testsuite:
* c-c++-common/auto-init-7.c, c-c++-common/auto-init-8.c: Also
match targets where sizeof (union U) == 5, like "packed" targets.
