We were allowing extra immediate arguments, and only bothering to check if registers were implicit or not. Also consolidate extra operand checks in verifier, to make this testable. We had 3 different places checking if you were trying to build an instruction with more operands than allowed by the definition. We had an assertion in addOperand, a direct check in the MIRParser to avoid the assertion, and the machine verifier checks. Remove the assert and parser check so the verifier can provide a consistent verification experience, which will also handle instructions modified in place.
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
