X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b6cd5d100a3ecc80f35d667063f94c98bdfbf20a;p=binutils-gdb.git

x86: Process ImmExt without operands

To support Intel AMX instructions with 8-bit immediate opcode extension,
but without operands:

tilerelease, 0, 0x49, 0xc0, 1, CpuAMX_TILE|Cpu64, Vex|VexOpcode=1|No_bSuf|No_wSuf|No_lSuf|No_sSuf|No_qSuf|No_ldSuf|ImmExt, { 0 }

process ImmExt without operands.

	* config/tc-i386.c (md_assemble): Process ImmExt without
	operands.
