[IR] Remove FP cast constant expressions (#71408)

2023-11-07T08:34:16+00:00

Remove support for the fptrunc, fpext, fptoui, fptosi, uitofp and sitofp
constant expressions. All places creating them have been removed
beforehand, so this just removes the APIs and uses of these constant
expressions in tests.

With this, the only remaining FP operation that still has constant
expression support is fcmp.

[IR] Remove zext and sext constant expressions (#71040)

2023-11-03T09:46:07+00:00

Remove support for zext and sext constant expressions. All places
creating them have been removed beforehand, so this just removes the
APIs and uses of these constant expressions in tests.

There is some additional cleanup that can be done on top of this, e.g.
we can remove the ZExtInst vs ZExtOperator footgun.

Make "@name =" mandatory for globals in .ll files.

2016-05-10T18:22:45+00:00

An oddity of the .ll syntax is that the "@var = " in

@var = global i32 42

is optional. Writing just

global i32 42

is equivalent to

@0 = global i32 42

This means that there is a pretty big First set at the top level. The
current implementation maintains it manually. I was trying to refactor
it, but then started wondering why keep it a all. I personally find the
above syntax confusing. It looks like something is missing.

This patch removes the feature and simplifies the parser.

[opaque pointer type] Add textual IR support for explicit type parameter to gep operator

2015-03-13T18:20:45+00:00

Similar to gep (r230786) and load (r230794) changes.

Similar migration script can be used to update test cases, which
successfully migrated all of LLVM and Polly, but about 4 test cases
needed manually changes in Clang.

(this script will read the contents of stdin and massage it into stdout
- wrap it in the 'apply.sh' script shown in previous commits + xargs to
apply it over a large set of test cases)

import fileinput
import sys
import re

rep = re.compile(r"(getelementptr(?:\s+inbounds)?\s*\()((<\d*\s+x\s+)?([^@]*?)(|\s*addrspace\(\d+\))\s*\*(?(3)>)\s*)(?=$|%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|zeroinitializer|<|\[\[[a-zA-Z]|\{\{)", re.MULTILINE | re.DOTALL)

def conv(match):
  line = match.group(1)
  line += match.group(4)
  line += ", "
  line += match.group(2)
  return line

line = sys.stdin.read()
off = 0
for match in re.finditer(rep, line):
  sys.stdout.write(line[off:match.start()])
  sys.stdout.write(conv(match))
  off = match.end()
sys.stdout.write(line[off:])

For PR1258:

Revise numeric value references to accommodate collapsed type planes.

For PR761:

2007-01-26T08:25:06+00:00

Remove "target endian/pointersize" or add "target datalayout" to make
the test parse properly or set the datalayout because defaults changes.

For PR645:
Make global names use the @ prefix.

For llvm-upgrade changes:
Fix test cases or completely remove use of llvm-upgrade for test cases
that cannot survive the new renaming or upgrade capabilities.
