[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

[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

[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

[ARM] Add Virtualization subtarget feature and more build attributes in this area Add a Virtualization ARM subtarget feature along with adding proper build attribute emission for Tag_Virtualization_use (encodes Virtualization and TrustZone) and Tag_MPextension_use. Also rework test/CodeGen/ARM/2010-10-19-mc-elf-objheader.ll testcase to something that is more maintainable. This changes the focus of this testcase away from testing CPU defaults (which is tested elsewhere), onto specifically testing that attributes are encoded correctly. llvm-svn: 193859
