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: unassig...@gcc.gnu.org ReportedBy: ja...@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
