Logan Chien 043426ee56 [arm] Implement eabi_attribute, cpu, and fpu directives. ... This commit allows the ARM integrated assembler to parse and assemble the code with .eabi_attribute, .cpu, and .fpu directives. To implement the feature, this commit moves the code from AttrEmitter to ARMTargetStreamers, and several new test cases related to cortex-m4, cortex-r5, and cortex-a15 are added. Besides, this commit also change the Subtarget->isFPOnlySP() to Subtarget->hasD16() to match the usage of .fpu directive. This commit changes the test cases: * Several .eabi_attribute directives in 2010-09-29-mc-asm-header-test.ll are removed because the .fpu directive already cover the functionality. * In the Cortex-A15 test case, the value for Tag_Advanced_SIMD_arch has be changed from 1 to 2, which is more precise. llvm-svn: 193524		2013-10-28 17:51:12 +00:00
