TableGen: fix operand counting for aliases TableGen has a fairly dubious heuristic to decide whether an alias should be printed: does the alias have lest operands than the real instruction. This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars. There are basically 4 changes this brings about after the previous commits; all of these appear to be good, so I have changed the tests: + ARM64: we print "neg X, Y" instead of "sub X, xzr, Y". + ARM64: we skip implicit "uxtx" and "uxtw" modifiers. + Sparc: we print "mov A, B" instead of "or %g0, A, B". + Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B" llvm-svn: 208969

Add AArch64 as an experimental target. This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054

Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258

This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars. There are basically 4 changes this brings about after the previous commits; all of these appear to be good, so I have changed the tests: + ARM64: we print "neg X, Y" instead of "sub X, xzr, Y". + ARM64: we skip implicit "uxtx" and "uxtw" modifiers. + Sparc: we print "mov A, B" instead of "or %g0, A, B". + Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B" llvm-svn: 208969

Add AArch64 as an experimental target. This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054

AArch64: Make test more robust. Avoid the creation of select instructions which can result in different scheduling of the selects. I also added a bunch of additional store volatiles. Those avoid A CodeGen problem (bug?) where normalizes and denomarlizing the control moves all shift instructions into the first block where ISel can't match them together with the cmps. llvm-svn: 228362

Add AArch64 as an experimental target. This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054

Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives.

TableGen: fix operand counting for aliases TableGen has a fairly dubious heuristic to decide whether an alias should be printed: does the alias have lest operands than the real instruction. This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars. There are basically 4 changes this brings about after the previous commits; all of these appear to be good, so I have changed the tests: + ARM64: we print "neg X, Y" instead of "sub X, xzr, Y". + ARM64: we skip implicit "uxtx" and "uxtw" modifiers. + Sparc: we print "mov A, B" instead of "or %g0, A, B". + Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B" llvm-svn: 208969
