Summary:
GNU strip supports both `-s` and `-S` as aliases for `--strip-all` and `--strip-debug`, respectfully.

As part of this, it turns out that strip/objcopy were accepting case insensitive command line args. I'm not sure if there was an explicit reason for this. The only others uses of this are llvm-cvtres/llvm-mt/llvm-lib, which are all tools specific for windows support. Forcing case sensitivity allows both aliases to exist, but seems like a good idea anyway.

And as a surprise test case adjustment, the llvm-strip unit test was running with `-keep=unavailable_symbol`, despite `keep` not be a valid flag for strip. This is because there is a flag `-K` which, when case insensitivity is permitted, allows it to be interpreted as `-K` = `eep=unavailable_symbol` (e.g. to allow `-Kfoo` == `--keep-symbol=foo`).

Summary:
Some targets have very long encodings and uint64_t isn't sufficient. uint128_t
isn't portable so such targets need to use an object instead.

There is one catch with this at the moment, no string of bits extracted
from the encoding may exceeed 64-bits. Fields are still permitted to
exceed 64-bits so long as they aren't one contiguous string of bits. If
this proves to be a problem then we can modify the generation of
fieldFromInstruction() calls to account for it but for now I've added an
assertion for this.

InsnType must either be integral or an APInt-like object that must:
* Have a static const max_size_in_bits equal to the number of bits in the encoding.
* be default-constructible and copy-constructible
* be constructible from a uint64_t (this is the key area the interface deviates
  from APInt since this constructor does not take the bit width)
* be constructible from an APInt (this can be private)
* be convertible to uint64_t
* Support the ~, &,, ==, !=, and |= operators with other objects of the same type
* Support shift (<<, >>) with signed and unsigned integers on the RHS
* Support put (<<) to raw_ostream&

5 years ago[PDB] Improve performance of the PDB DIA plugin
Aleksandr Urakov [Tue, 23 Oct 2018 08:29:17 +0000 (08:29 +0000)]
[PDB] Improve performance of the PDB DIA plugin

Summary:
This patch improves performance of `SymbolFilePDB` on huge executables
in two ways:

- cache names of public symbols by address. When creating variables we are
  trying to get a mangled name for each one, and in `GetMangledForPDBData`
  we are enumerating all public symbols, which takes O(n) for each variable.
  With the cache we can retrieve a mangled name in O(log(n));

- cache section contributions. When parsing variables for context we are
  enumerating all variables and check if the current one is belonging
  to the current compiland. So we are retrieving a compiland ID
  for the variable. But in `PDBSymbolData::getCompilandId` for almost every
  variable we are enumerating all section contributions to check if the variable
  is belonging to it, and get a compiland ID from the section contribution
  if so. It takes O(n) for each variable, but with caching it takes about
  O(log(n)). I've placed the cache in `SymbolFilePDB` and have created
  `GetCompilandId` there. It actually duplicates `PDBSymbolData::getCompilandId`
  except for the cache part. Another option is to support caching
  in `PDBSymbolData::getCompilandId` and to place cache in `DIASession`, but it
  seems that the last one doesn't imply such functionality, because
  it's a lightweight wrapper over DIA and whole its state is only a COM pointer
  to the DIA session. Moreover, `PDBSymbolData::getCompilandId` is used only
  inside of `SymbolFilePDB`, so I think that it's not a bad place to do such
  things. With this patch `PDBSymbolData::getCompilandId` is not used at all.

This bottlenecks were found with profiling. I've discovered these on a simple
demo project of Unreal Engine (x86 executable ~72M, PDB ~82M).

This patch doesn't change external behavior of the plugin, so I think that
there's no need for additional testing (already existing tests should warn us
about regress, if any).

[AST] Do not align virtual bases in `MicrosoftRecordLayoutBuilder` when
      an external layout is used

Summary:
The patch removes alignment of virtual bases when an external layout is used.
We have two cases:
- the external layout source has an information about virtual bases offsets,
  so we just use them;
- the external source has no information about virtual bases offsets. In this
  case we can't predict where the base will be located. If we will align it but
  there will be something like `#pragma pack(push, 1)` really, then likely our
  layout will not fit into the real structure size, and then some asserts will
  hit. The asserts look reasonable, so I don't think that we need to remove
  them. May be it would be better instead don't align fields / bases etc.
  (so treat it always as `#pragma pack(push, 1)`) when an external layout source
  is used but no info about a field location is presented.

This one is related to D49871

[Driver] Use forward slashes in most linker arguments

libtool inspects the output of $CC -v to detect what object files and
libraries are linked in by default. When clang is built as a native
windows executable, all paths are formatted with backslashes, and
the backslashes cause each argument to be enclosed in quotes. The
backslashes and quotes break further processing within libtool (which
is implemented in shell script, running in e.g. msys) pretty badly.

Between unix style pathes (that only work in tools that are linked
to the msys runtime, essentially the same as cygwin) and proper windows
style paths (with backslashes, that can easily break shell scripts
and msys environments), the best compromise is to use windows style
paths (starting with e.g. c:) but with forward slashes, which both
msys based tools, shell scripts and native windows executables can
cope with. This incidentally turns out to be the form of paths that
GCC prints out when run with -v on windows as well.

This change potentially makes the output from clang -v a bit more
inconsistent, but it is isn't necessarily very consistent to begin with.

Don't mess up RelIplt symbols during relocatable processing

Summary:
During upgrading of the FreeBSD source tree with lld 7.0.0, I noticed
that it started complaining about `crt1.o` having an "index past the
end of the symbol table".

Such a symbol table looks approximately like this, viewed with `readelf
-s` (note the `Ndx` field being messed up):

```
Symbol table '.symtab' contains 4 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name
     0: 00000000     0 NOTYPE  LOCAL  DEFAULT  UND
     1: 00000000     0 SECTION LOCAL  DEFAULT    1
     2: 00000000     0 NOTYPE  WEAK   HIDDEN  RSV[0xffff] __rel_iplt_end
     3: 00000000     0 NOTYPE  WEAK   HIDDEN  RSV[0xffff] __rel_iplt_start
```

At first, it seemed that recent ifunc relocation work had caused this:
<https://reviews.freebsd.org/rS339351>, but it turned out that it was
due to incorrect processing of the object files by lld, when using `-r`
(a.k.a. --relocatable).

Bisecting showed that rL324421 ("Convert a use of Config->Static") was
the commit where this new behavior began.  Simply reverting it solved
the issue, and the `__rel_iplt` symbols had an index of `UND` again.

Looking at Rafael's commit message, I think he simply missed the
possibility of `--relocatable` being in effect, so I have added an
additional check for it.

I also added a simple regression test case.
