[NFC] remove explicit default value for strboolattr attribute in tests

2021-05-24T17:31:04+00:00

Since d6de1e1a71406c75a4ea4d5a2fe84289f07ea3a1, no attributes is quivalent to
setting attribute to false.

This is a preliminary commit for https://reviews.llvm.org/D99080

Migrate function attribute "no-frame-pointer-elim-non-leaf" to "frame-pointer"="non-leaf" as cleanups after D56351

[PowerPC] Fix assert from machine verify pass that missing undef register flag

2018-12-07T05:25:16+00:00

Fix assert about using an undefined physical register in machine instruction verify pass. 
The reason is that register flag undef is missing when doing transformation from If Conversion Pass.

```
Bad machine code: Using an undefined physical register 
- function:    func_65
- basic block: %bb.0 entry (0x10024740738)
- instruction: BCLR killed $cr5lt, implicit $lr8, implicit $rm, implicit undef $x3
- operand 0:   killed $cr5lt
LLVM ERROR: Found 1 machine code errors.
```

There are also other existing testcases with same issue. So I add -verify-machineinstrs option to open verifying.

Cleanup initial-value constants in PPCCTRLoops

2013-03-18T17:40:27+00:00

Because the initial-value constants had not been added to the list
of instructions considered for DCE the resulting code had redundant
constant-materialization instructions.
