GISel: Canonicalize select tests using update_mir_test_checks This runs `udpate_mir_test_checks --add-vreg-checks` on the tests taht are already more or less in the format that generates, so that there will be less churn in some upcoming changes. llvm-svn: 316139

[globalisel] Remove redundant -global-isel option from tests that use -run-pass. NFC As Roman Tereshin pointed out in https://reviews.llvm.org/D45541, the -global-isel option is redundant when -run-pass is given. -global-isel sets up the GlobalISel passes in the pass manager but -run-pass skips that entirely and configures it's own pipeline. llvm-svn: 331603

Re-commit: [globalisel][tablegen] Support zero-instruction emission. Summary: Support the case where an operand of a pattern is also the whole of the result pattern. In this case the original result and all its uses must be replaced by the operand. However, register class restrictions can require a COPY. This patch handles both cases by always emitting the copy and leaving it for the register allocator to optimize. The previous commit failed on Windows machines due to a flaw in the sort predicate which allowed both A < B < C and B == C to be satisfied simultaneously. The cause of this was some sloppiness in the priority order of G_CONSTANT instructions compared to other instructions. These had equal priority because it makes no difference, however there were operands had higher priority than G_CONSTANT but lower priority than any other instruction. As a result, a priority order between G_CONSTANT and other instructions must be enforced to ensure the predicate defines a strict weak order.

MIR: Print the register class or bank in vreg defs This updates the MIRPrinter to include the regclass when printing virtual register defs, which is already valid syntax for the parser. That is, given 64 bit %0 and %1 in a "gpr" regbank, %1(s64) = COPY %0(s64) would now be written as %1:gpr(s64) = COPY %0(s64) While this change alone introduces a bit of redundancy with the registers block, it allows us to update the tests to be more concise and understandable and brings us closer to being able to remove the registers block completely. Note: We generally only print the class in defs, but there is one exception. If there are uses without any defs whatsoever, we'll print the class on all uses. I'm not completely convinced this comes up in meaningful machine IR, but for now the MIRParser and MachineVerifier both accept that kind of stuff, so we don't want to have a situation where we can print something we can't parse. llvm-svn: 316479

MIR: Print the register class or bank in vreg defs This updates the MIRPrinter to include the regclass when printing virtual register defs, which is already valid syntax for the parser. That is, given 64 bit %0 and %1 in a "gpr" regbank, %1(s64) = COPY %0(s64) would now be written as %1:gpr(s64) = COPY %0(s64) While this change alone introduces a bit of redundancy with the registers block, it allows us to update the tests to be more concise and understandable and brings us closer to being able to remove the registers block completely. Note: We generally only print the class in defs, but there is one exception. If there are uses without any defs whatsoever, we'll print the class on all uses. I'm not completely convinced this comes up in meaningful machine IR, but for now the MIRParser and MachineVerifier both accept that kind of stuff, so we don't want to have a situation where we can print something we can't parse. llvm-svn: 316479

Re-commit: [globalisel][tablegen] Support zero-instruction emission. Summary: Support the case where an operand of a pattern is also the whole of the result pattern. In this case the original result and all its uses must be replaced by the operand. However, register class restrictions can require a COPY. This patch handles both cases by always emitting the copy and leaving it for the register allocator to optimize. The previous commit failed on Windows machines due to a flaw in the sort predicate which allowed both A < B < C and B == C to be satisfied simultaneously. The cause of this was some sloppiness in the priority order of G_CONSTANT instructions compared to other instructions. These had equal priority because it makes no difference, however there were operands had higher priority than G_CONSTANT but lower priority than any other instruction. As a result, a priority order between G_CONSTANT and other instructions must be enforced to ensure the predicate defines a strict weak order.
