[PATCH] x32: Generate 0x67 prefix for VSIB address without base
- From: "H.J. Lu" <hjl dot tools at gmail dot com>
- To: binutils at sourceware dot org

- Subject: [PATCH] x32: Generate 0x67 prefix for VSIB address without base
In x32, add ADDR_PREFIX_OPCODE prefix for VSIB address without base
register so that vector index register won't be sign-extended to 64 bits.
We can't have ADDR_PREFIX_OPCODE prefix for VSIB if there is segment
override since address will be segment override + zero-extended to 64
bits of (base + index * scale + disp).
PR gas/24263
* config/tc-i386.c (output_insn): In x32, add 0x67 address size
prefix for VSIB address without base register and issue an error
if there is segment override with ADDR_PREFIX_OPCODE prefix.
* testsuite/gas/i386/ilp32/ilp32.exp: Run x86-64-avx-vsib-inval.
