- Subject: support for extensa mul16, fp, etc ?
Does binutils-2.15, with the xtensa target,
have support for the 'optional' instruction
sets, e.f. mul16 option, fpu option, etc?
Because gcc-3.4.1 does .. and my gcc build is
failing due to the assembler not recognizing
the 'mul16u' instruction. I have placed
identical 'xtensa_config.h' files in the
include dirs for gcc and binutils, but
binutils appears to be ignoring XCHAL_HAVE_MUL16,
XCHAL_HAVE_FP, etc, furthermore I don't see
the opcodes in xtensa-modules.c .
How is the gcc supported for these instructions
sets ?
