s390x: Fix s390_md_asm_adjust handling of long doubles [PR112753]
Commit 466b100e5fee808d77598e0f294654deec281150 introduced a bug in
s390_md_asm_adjust if vector extensions are not available. Fix the
control flow of this function to not adjust long double values.
gcc/ChangeLog:
PR target/112753
* config/s390/s390.cc (s390_md_asm_adjust): Return after dealing
with the outputs, if no further processing of long doubles is
required.
gcc/testsuite/ChangeLog:
* gcc.target/s390/pr112753.c: New test.
