Bug ID: 65671
Summary: Assembly failure (invalid register operand) with -O3
-mavx512vl
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jamrial at gmail dot com

gcc -O3 -mavx512f -mavx512vl -c -o libdcadec/idct_float.o

/tmp/cc3BQBvH.s:1670: Error: invalid register operand for `vextractf128'
Lines in question from the resulting assembly file
1602: vextractf128 $0x1, %ymm20, 144(%rdx)
1624: vextractf128 $0x1, %ymm24, 272(%rdx)
1670: vextractf128 $0x1, %ymm19, 400(%rdx)
GCC 5.0.0 (20150329 snapshot) on x86_64-unknown-linux-gnu. Works fine with
-mavx512f alone, so sounds like the assembler is trying to use VEX coding
scheme with the new registers instead of EVEX.
