Has anyone converted llvm/projects/test-suite to use the llvm assembler instead of gcc? If so, what was needed to change and how? My assumption is that this would be a good way to test the llvm assembler. Jack -------------- next part -------------- An HTML attachment was scrubbed...

I'm trying to generate MipsGenAsmMatcher.inc for MipsAsmParser.cpp. What added restrictions for the .td file contents are there for tblgen -gen-asm-matcher? For the Mips platform we create the following .inc files through tblgen. tablegen(LLVM MipsGenRegisterInfo.inc -gen-register-info) tablegen(LLVM MipsGenInstrInfo.inc -gen-instr-info) tablegen(LLVM MipsGenCodeEmitter.inc -gen-emitter)

Is there an official llvm method of creating and submitting test cases that don't affect .s assembly files? When we check in changes that can affect the .s output we submit .ll files with the internalized semicolon instructions on how to check the output .s file. For direct output we currently add to our own test suites that check for correctness. Does the llvm community depend on the

There are times that I want to generate an ERROR, but not stop processing of the code. An example of this would be when I find there is a value out of range for a specific operand. producing the error for all instances of this class of errors would be good. Also, I would like to have the error message have some relationship to the offending source. Thanks, Jack -------------- next part

In my experience assertions are a development tool and should not be a part of the user's experience. With that in mind, do we expect the end user to ever invoke llc directly? The reason I ask is that I directly gave llc some bogus command line input and it asserted. Is it a bug that a graceful error message and exit from llc wasn't performed or is it considered "fair game" to

I've made a change to llvm-objdump and feel uncomfortable checking it in without a test case. Where do the "make check" tests for tools like llvm-objdump go? Worse comes to worse, I'll stick it in test/MC/Mips since it is there I need the change for other Mips/MC tests.
