Eric Christopher	661f2d1ca1	Add a new string member to the TargetOptions struct for the name of the abi we should be using. For targets that don't use the option there's no change, otherwise this allows external users to set the ABI via string and avoid some of the -backend-option pain in clang. Use this option to move the ABI for the ARM port from the Subtarget to the TargetMachine and update the testcases accordingly since it's no longer valid to set via -mattr. llvm-svn: 224492	2014-12-18 02:20:58 +00:00
Eric Christopher	1971c3508a	Model ARM backend ABI selection after the front end code doing the same. This will change the "bare metal" ABI from APCS to AAPCS. The only difference between the front and back end code is that the code for Triple::GNU was added for environment. That will migrate to the front end shortly. Tests updated with the ABI they were originally testing in the case of bare metal (e.g. -mtriple armv7) or with a -gnu for arm-linux triples. llvm-svn: 224489	2014-12-18 02:08:45 +00:00

Add a new string member to the TargetOptions struct for the name

of the abi we should be using. For targets that don't use the
option there's no change, otherwise this allows external users
to set the ABI via string and avoid some of the -backend-option
pain in clang.

Use this option to move the ABI for the ARM port from the
Subtarget to the TargetMachine and update the testcases
accordingly since it's no longer valid to set via -mattr.

Make the ARM ABI selectable via SubtargetFeature.

This patch makes it possible to select the ABI with -mattr. It will be used to
forward clang's -target-abi option to llvm's CodeGen.
