Shiva Chen	53489ada12	[RISCV] Add ELFObjectFileBase::getRISCVFeatures let llvm-objdump could get RISCV target feature ... llvm-objdump could get C feature by ELF::EF_RISCV_RVC e_flag, so then we don't have to add -mattr=+c on the command line.

Ana Pazos	1b57c7a0f4	[RISCV] Fixed setting predicates for compressed instructions. ... Summary: Fixed setting predicates for compressed instructions. Some instructions were being generated with C extension enabled only, without proper checks for the other required extensions like F, D and 32 and 64-bit target checks. Affected instructions: C_FLD, C_FLW, C_LD, C_FSD, C_FSW, C_SD, C_JAL, C_ADDIW, C_SUBW, C_ADDW, C_FLDSP, C_FLWSP, C_LDSP, C_FSDSP, C_FSWSP, C_SDSP Reviewers: asb, shiva0217 Reviewed By: asb Subscribers: rbar, johnrusso, simoncook, jordy.potman.lists, sabuasal, niosHD, llvm-commits Differential Revision: https://reviews.llvm.org/D42132 llvm-svn: 322876	2018-01-18 18:54:05 +00:00
Alex Bradbury	59136ffab1	[RISCV] Enable emission of alias instructions by default ... This patch switches the default for -riscv-no-aliases to false and updates all affected MC and CodeGen tests. As recommended in D41071, MC tests use the canonical instructions and the CodeGen tests use the aliases. Additionally, for the f and d instructions with rounding mode, the tests for the aliased versions are moved and tightened such that they can actually detect if alias emission is enabled.
