Bug ID: 27626
Summary: the "fix" for bug 25622 actually broke things
Product: binutils
Version: 2.36.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: jbeulich at suse dot com
Target Milestone: ---
Working around a compiler issue by suppressing legitimate assembler warnings is
not a way to go. In fact the suppressed warnings hide a code generation bug in
gcc (up to 7 afaict) - in such a case, it seems more than just desirable to me
to point out to the programmer that the compiler produced bad code. The issue
there was a lack of suffix in "cvtusi2<ssescalarmodesuffix>32<round_name>" and
"cvtusi2<ssescalarmodesuffix>64<round_name>", which is leading to a 32-bit
source operand getting used silently in the 64-bit case.
The correct way to approach such problems is to backport the respective fixes
to the affected older compiler branches. The gas change (commit 10d97a0f9907)
should be reverted.
