Bug #: 56091
Summary: gcc.target/arm/pr43137.c fails for THUMB-1
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: janis@gcc.gnu.org
Target: arm-none-eabi
This test failure now appears for mainline arm-none-eabi for all THUMB-1
effective targets:
FAIL: gcc.target/arm/pr43137.c scan-assembler-not movtr1, r[1-9]
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 failure begins with this patch to GCC mainline:
r187015 | rsandifo | 2012-05-01 07:45:24 -0700 (Tue, 01 May 2012) | 33 lines
This is a regression from GCC 4.7

The patch made lower_subreg take rtx_costs into account, so some targets' rtx_costs might need updating. ^ permalink raw reply [flat|nested] 4+ messages in thread

If you can reproduce this with any maintained version of gcc please reopen with the relevant details. RTX costs for arm have been rewritten quite extensively for 4.9 btw ^ permalink raw reply [flat|nested] 4+ messages in thread
