Bug ID: 64323
Summary: LRA: ICE when compiling newlib for ARM.
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: Hale.Wang at arm dot com
Created attachment 34287
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34287&action=edit
This temp file is generated from newlib/newlib/libc/stdlib/dtoa.c.
When compiling the newlib stdlib for ARM, GCC 5.0 reported:
newlib/newlib/libc/stdlib/dtoa.c:862:1: error: unable to generate reloads for:
(insn 2301 287 2302 16 (set (reg:CCFP 101 vfpcc)
(compare:CCFP (reg:DF 217 [ D.6454 ])
(const_double:DF 0.0 [0x0.0p+0])))
.../newlib/newlib/libc/stdlib/dtoa.c:282 679 {*cmpdf_vfp}
(nil))
/work/tools/gcc-arm-none-eabi-5_0-2014q4-20141211/src/newlib/newlib/libc/stdlib/dtoa.c:862:1:
internal compiler error: in curr_insn_transform, at lra-constraints.c:3383
The command line is:
arm-none-eabi-gcc -marm -O2 -mfloat-abi=hard dtoa.i
I have attached the temp file 'dtoa.i'. If I added the -mno-lra option, there
was no error.

Maybe this was fixed by Vladimir's commit r218760?
