Bug #: 56092
Summary: gcc.target/arm/volatile-bitfields-1.c fails for THUMB
and armv[78]
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/volatile-bitfields-1.c scan-assembler ldrb[\t
]+[^n]*,[\t ]*\[[^n]*\]
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. The test fails for THUMB-1 and THUMB-2, and for armv7a, armv7r,
and armv8a in ARM mode.
The test failure begins with this patch to GCC mainline:
r193605 | rsandifo | 2012-11-18 09:33:38 -0800 (Sun, 18 Nov 2012) | 37
lines
This is a regression from GCC 4.7.
