- Subject: [PATCH][ARM]Add armv7ve architecture support to gas
- Authentication-results: sourceware.org; auth=none
Hello all,
This patch will add new arch option armv7ve to gas. armv7ve is basically
a armv7-a architecture profile with Virtualization Extensions.
"-march=armv7ve" has the same effect as
"-march=armv7-a+virt+sec+idiv+mp" in the command line.
In the assembler code, the following configurations have the same effects:
.arch armv7ve
=====or=======
.arch armv7-a
.arch_extension idiv
.arch_extension mp
.arch_extension sec
.arch_extension virt
A small test case is also added.
This has been tested for arm-none-linux-gnueabi on the model.
Okay for trunk?
Kind regards,
Renlin Li
Add support for armv7ve to gas.
gas/ChangeLog:
2013-11-11 Renlin Li <Renlin.Li@arm.com>
* config/tc-arm.c (arm_archs): New armv7ve architecture option.
(arm_cpus): Replace ARM_ARCH_V7A_IDIV_MP_SEC_VIRT with
ARM_ARCH_V7VE for cortex-a7, cortex-a12 and cortex-a15.
(cpu_arch_ver): Likewise.
* doc/c-arm.texi: Document armv7ve.
gas/testsuite/ChangeLog:
2013-11-1 Renlin Li <Renlin.Li@arm.com>
* gas/arm/attr-march-armv7ve.d: New test case for armv7ve.
include/opcode/ChangeLog:
2013-11-11 Renlin Li <Renlin.Li@arm.com>
* arm.h (ARM_AEXT_V7VE): New define.
(ARM_ARCH_V7VE): New define.
(ARM_ARCH_V7A_IDIV_MP_SEC_VIRT): Removed.diff --git a/gas/config/tc-arm.c b/gas/config/tc-arm.c
