These tests have been disabled on Linux and Windows due to failing
there. I think that could be down to a race condition between stdout
and stderr, so I have disabled output to stdout.
For the moment, only re-enable on linux, because I don't have a windows
machine to test on.

Because they fail there too.

We were getting test failures on some builders, which pointed to @LINE
being an undefined variable. I think that these failures should have
been fixed by https://reviews.llvm.org/rL366434, so I'm re-enabling the
test.

Patch by John LLVM (JohnLLVM)
llvm-svn: 365881
Match the GNU assembler in supporting immediate operands for these
instructions even when the reg-reg mnemonic is used.
Differential Revision: https://reviews.llvm.org/D50046
Patch by Kito Cheng.
llvm-svn: 339252
The implementation follows the MIPS backend and expands the pseudo instruction
directly during asm parsing. As the result, only real MC instructions are
emitted to the MCStreamer. The actual expansion to real instructions is
similar to the expansion performed by the GNU Assembler.
This patch supersedes D41949.

Patch by Mario Werner.
llvm-svn: 334203
Reverts rL330224, while issues with the C extension and missed common
subexpression elimination opportunities are addressed. Neither of these issues
are visible in current RISC-V backend unit tests, which clearly need
expanding.
llvm-svn: 330281
The implementation follows the MIPS backend and expands the
pseudo instruction directly during asm parsing. As the result, only
real MC instructions are emitted to the MCStreamer. Additionally,
PseudoLI instructions are emitted during codegen. The actual
expansion to real instructions is performed during MI to MC lowering
and is similar to the expansion performed by the GNU Assembler.

Patch by Mario Werner.
llvm-svn: 330224
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.
(see D40902 for context)
Differential Revision: https://reviews.llvm.org/D41225
Patch by Mario Werner.
llvm-svn: 320797
Adds the assembler pseudo instructions of RV32I and RV64I which can
be mapped to a single canonical instruction. The missing pseudo
instructions (e.g., call, tail, ...) are marked as TODO. Other
things, like for example PCREL_LO, have to be implemented first.
Currently, alias emission is disabled by default to keep the patch
minimal. Alias emission by default will be enabled in a subsequent
patch which also updates all affected tests. Note that this patch
should actually break the floating point MC tests. However, the
used FileCheck configuration is not tight enought to detect the
breakage.
