The LIT test cases were migrated with the script provided by
Nikita Popov. Due to the size of the change it is split into
several parts.

PowerPC: Do not use llc -march in tests.

2017-08-01T22:20:41+00:00

`llc -march` is problematic because it only switches the target
architecture, but leaves the operating system unchanged. This
occasionally leads to indeterministic tests because the OS from
LLVM_DEFAULT_TARGET_TRIPLE is used.

However we can simply always use `llc -mtriple` instead. This changes
all the tests to do this to avoid people using -march when they copy and
paste parts of tests.

This patch:
- Removes -march if the .ll file already has a matching `target triple`
  directive or -mtriple argument.
- In all other cases changes -march=ppc32/-march=ppc64 to
  -mtriple=ppc32--/-mtriple=ppc64--

Adding -verify-machineinstrs option to PowerPC tests

2016-08-03T18:17:35+00:00

Currently we have a number of tests that fail with -verify-machineinstrs.
To detect this cases earlier we add the option to the testcases with the
exception of tests that will currently fail with this option. PR 27456 keeps
track of this failures.

No code review, as discussed with Hal Finkel.

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction

2015-02-27T21:17:42+00:00

Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

import fileinput
import sys
import re

pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")

for line in sys.stdin:
  sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

Split the Add, Sub, and Mul instruction opcodes into separate

2009-06-04T22:49:04+00:00

integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Help DejaGnu avoid pipe-jam by producing less output from certain test cases.

2009-05-16T00:34:42+00:00

When a test fails with more than a pipeful of output on stdout AND stderr, one
of the DejaGnu programs blocks. The problem can be avoided by redirecting
stdout to a file.
