Bug ID: 65924
Summary: [6.0 Regression] ICE const_int_operand failed on
arm-none-eabi
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: yroux at gcc dot gnu.org
Target Milestone: ---
My insn cleanup patch committed at r222528 brakes newlib build when compiling
ldtoa.c. I didn't notice it earlier as newlib has to be built in thumb. I'll
fix that.
Error message is:
ldtoa.c:2857:1: internal compiler error: Segmentation fault
