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

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

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
