Bug #: 56093
Summary: gcc.target/arm/wmul-11.c fails for armv5te and iwmmxt
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ja...@gcc.gnu.org
Target: arm-none-eabi
This test failure now appears for mainline arm-none-eabi:
FAIL: gcc.target/arm/wmul-11.c scan-assembler smull
This is a compile-only test so I was able to run it for 34 sets of flags
comprising all values of -march supported by GAS, with and without -mthumb as
appropriate. It now fails for armv5te, iwmmxt, and iwmmxt2. The test is
skipped if the effective target is not arm_dsp.
The test failure begins with this patch to GCC mainline:
r190050 | rth | 2012-08-01 13:26:58 -0700 (Wed, 01 Aug 2012) | 1 line
Allow MODE_PARTIAL_INT in expmed costs
This is a regression from GCC 4.7.
