2020-02-19[UpdateTestChecks] Add support for '.' in ir function namesSimon Pilgrim1-1/+1
Will let us regenerate from amdgpu float constant tests
2020-02-11[Utils] Allow "on-the-fly" argument changes for update_test_check scriptsJohannes Doerfert1-0/+26
Update test scripts were limited because they performed a single action on the entire file and if that action was controlled by arguments, like the one introduced in D68819, there was no record of it. This patch introduces the capability of changing the arguments passed to the script "on-the-fly" while processing a test file. In addition, an "on/off" switch was added so that processing can be disabled for parts of the file where the content is simply copied. The last extension is a record of the invocation arguments in the auto generated NOTE. These arguments are also picked up in a subsequent invocation, allowing updates with special options enabled without user interaction. To change the arguments the string `UTC_ARGS:` has to be present in a line, followed by "additional command line arguments". That is everything that follows `UTC_ARGS:` will be added to a growing list of "command line arguments" which is reparsed after every update.

2020-01-02update_test_checks: match CHECK-EMPTY lines for replacement.James Y Knight1-1/+1
In a8a89c77ea3c16b45763fca6940bbfd3bef7884f, the script started adding CHECK-EMPTY lines, but the regex for which lines to replace was not updated.
2019-12-31[Utils] Deal with occasionally deleted functionsJohannes Doerfert1-4/+25
When functions exist for some but not all run lines we need to be careful when selecting the prefix. So far, a common prefix was potentially chosen as there was never a "conflict" that would have caused otherwise. With this patch we avoid common prefixes if they are used by run lines that do not emit the function. Reviewed By: lebedev.ri Differential Revision: https://reviews.llvm.org/D68850
2019-12-31[Utils] Reuse argument variable names in the bodyJohannes Doerfert1-4/+4
If we have `int foo(int a) { return a; }` and we run with --function-signature enabled, we want a single variable declaration for `a` which is reused later. Reviewed By: lebedev.ri Differential Revision: https://reviews.llvm.org/D69722
2019-12-31[Utils] Allow update_test_checks to scrub attribute annotationsJohannes Doerfert1-1/+3

2019-12-02[update_cc_test_checks.py] Use CHECK_RE from commonAlex Richardson1-1/+1
Summary: This change modifies the common.CHECK_RE regex to also handle '//' comment prefixes which allows us to share it between clang and IR tests. Using the regex from common means that *-SAME lines are also stripped now. Before this change using the --function-signature flag would result in -SAME: lines from previous runs not being removed.

Summary: Add a function common.parse_commandline_args() that adds options common to all tools (--verbose and --update-only) and returns the parsed commandline arguments. I plan to use the shared parsing of --verbose in a follow-up commit to remove most of the `if args.verbose:` checks in the scripts.

2019-11-01[Utils] Hide the default behavior change of D68819 under a flagJohannes Doerfert1-2/+2
With D69701, the options used when running the script on a file will be recorded and reused on a rerun. This allows us to hide new features behind flags, starting with the "define" that was introduced in D68819.
2019-11-01[utils] Reflow asm check generation to tolerate blank linesSimon Atanasyan1-1/+4
This change introduces two fixes. The second fix allows to generate a test to check the first fix. - Output `CHECK-EMPTY` prefix for an empty line in ASM output. Before that fix `update_llc_test_checks.py` incorrectly emits `CHECK-NEXT: <space>` prefix. - Fix the `ASM_FUNCTION_MIPS_RE` regex to stop on a real function epilogue not on an inline assembler prologue and include inline assembler code into a test.

2019-10-30[Utils] Allow update_test_checks to check function informationJohannes Doerfert1-11/+46
Summary: This adds a switch to the update_test_checks that triggers arguments and other function annotations, e.g., personality, to be present in the check line. If not set, the behavior should be the same as before. If arguments are recorded, their names are scrubbed from the IR to allow merging. This patch includes D68153.

2018-06-01[Utils][X86] Help update_llc_test_checks.py to recognise retl/retq to reduce ↵Simon Pilgrim1-9/+30
CHECK duplication (PR35003) This patch replaces the --x86_extra_scrub command line argument to automatically support a second level of regex-scrubbing if it improves the matching of nearly-identical code patterns. The argument '--extra_scrub' is there now to force extra matching if required. This is mostly useful to help us share 32-bit/64-bit x86 vector tests which only differs by retl/retq instructions, but any scrubber can now technically support this, meaning test checks don't have to be needlessly obfuscated. I've updated some of the existing checks that had been manually run with --x86_extra_scrub, to demonstrate the extra "ret{{[l|q]}}" scrub now only happens when useful, and re-run the sse42-intrinsics file to show extra matches - most sse/avx intrinsics files should be able to now share 32/64 checks. Tested with the opt/analysis scripts as well which share common code - AFAICT the other update scripts use their own versions. Differential Revision: https://reviews.llvm.org/D47485 llvm-svn: 333749

generation The script allows the auto-generation of checks for cost model tests to speed up their creation and help improve coverage, which will help a lot with PR36550. If the need arises we can add support for other analyze passes as well, but the cost models was the one I needed to get done - at the moment it just warns that any other analysis mode is unsupported. I've regenerated a couple of x86 test files to show the effect. Differential Revision: https://reviews.llvm.org/D45272 llvm-svn: 329390
