Hi,
Some one point out the root cause for the bug 54338
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54338
is that the IWMMXT_GR_REGS is not contained in ALL_REGS so that an assertion
fail is triggered in front end.
I checked the macro REG_CLASS_CONTENTS in arm.h and confirmed it.

Hi,
In neon.md, the define_expand "neon_vset_lane" has extra code to deal
with the imm operand when BYTE_BIG_ENDIAN,
unsigned int elt = INTVAL (operands[3]);
if (BYTES_BIG_ENDIAN)
{
unsigned int reg_nelts
= 64 / GET_MODE_BITSIZE (GET_MODE_INNER (mode));
elt ^= reg_nelt
