--- Comment #9 from Mikael Pettersson <mikpe at it dot uu.se> 2011-12-03 20:45:02 UTC --- Created attachment 25983 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25983 reduced test case in C The big test case easily reduced to the following snippet: void round_int(void) { __asm__ __volatile__("vmov.F64 d1,%0" : : "Dv"(0.5f) : "d1"); } Compiled with -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard -mfpu=vfpv3-d16 it ICEs trunk @ r181973 as follows: pr51381.c: In function 'round_int': pr51381.c:6:1: internal compiler error: in fp_immediate_constant, at config/arm/arm.c:13418 Current gcc 4.6 and 4.5 also ICE in fp_immediate_constant(). gcc-4.4 rejects the command line options (sorry, unimplemented: -mfloat-abi=hard and VFP).
