[PGO] cc1 option names change for profile instrumentation (NFC)

[xur]

Summary

This patch is split from http://reviews.llvm.org/D15829.

It changes cc1 option -fprofile-generate to an enum option -fprofile-instrument=,
and it takes Clang as the default (and only, or now) value.

It also changes cc1 options -fprofile-generate= to -fprofile-instrument-path=.

The driver level option -fprofile-generate and -fprofile-generate= are intact.

This change will pave the way to integrate new PGO instrumentation in IR level.

Perhaps: "Enable PGO instrumentation. The accepted value is Clang or None"

lib/Frontend/CompilerInvocation.cpp

481

Remove LLVM

[xur]

Updated the patch with David's comments. Also accept "None" as the -fprofile-instrument= value.

This is not accurate. It is not just for PGO.

lib/CodeGen/BackendUtil.cpp

432

Keep this as an if.

lib/CodeGen/CGStmt.cpp

1206

Is there a way to shorten this comparison? Can we add a helper like hasProfileClangInstr() or something instead of always having to do getProfileInstr() == CodeGenOptions::ProfileClangInstr? Otherwise, many of these comparisons read strange (such as the one in incrementProfileCounter, which is logically checking "is clang instr on or off", but the code as written makes it seem like it asking what kind of instr is being done).

lib/Frontend/CompilerInvocation.cpp

485

Please use lower case ("clang") for the option value, for consistency with other options.

[davidxl]

Add a test case for -fprofile-instrument=none and a negative case -fprofile-instrument=Garbage

[xur]

Integrated Sean and David review comments:

Note that the new test case to test
-fprofile-instrument=none and -fprofile-instrument=garbage are in tools/clang/test/Profile/c-generate.c.

Thanks,

-Rong

[davidxl]

This looks quite clean, but please wait for approval from one of other reviewers.

test/Profile/c-generate.c

Why are you not using %clang_cc1 consistently here?

4

|& doesn't seem to be used in other tests inside clang and llvm. A more portable alternative is probably required to pass the bots.

[davidxl]

test/Profile/c-generate.c

4

Should be safe to use 2>&1 | FileCheck -- there are existing test cases ..

[xur]

change test case test/Profile/c-generate.c:
(1) use clang_cc1
(2) use 2>&1

Thanks,

-Rong

ping.

[silvas]

Tiny nit, but this LGTM as well.

This : is inconsistently placed. (also for some of the other tablegen changes)

[xur]

Thanks Sean. I committed r260116 to fix the bad format for ':'.
