Another stab at fixing http://llvm.org/bugs/show_bug.cgi?id=12007.  I earlier missed that there are two common_type definitions and corrected only one of them.

For ELF, also call fixSymbolsInTLSFixups() on expressions passed to EmitValue (literal values). Previously only called on expressions in instructions. New test cases added to tls.s, tls-i386.s. Resolves PR11981.

llvm-svn: 150582

Remove reference from common_type definition.  It looks like a recent clang decltype implementation got fixed/improved and exposed this.  Fixes http://llvm.org/bugs/show_bug.cgi?id=12007.

world on Solaris 11 for both x86 and x86-64 using the built-in assembler and
Solaris (not GNU) ld, however it currently relies on a hard-coded GCC location
to find crtbegin.o and crtend.o, as well as libgcc and libgcc_eh.

This commit makes PrintfSpecifier::fixType() and ScanfSpecifier::fixType()
only fix a conversion specification enough that Clang wouldn't warn about it,
as opposed to always changing it to use the "canonical" conversion specifier.
(PR11975)

This preserves the user's choice of conversion specifier in cases like:

printf("%a", (long double)1);
where we previously suggested "%Lf", we now suggest "%La"

printf("%x", (long)1);
where we previously suggested "%ld", we now suggest "%lx".

The c'tor list is stored as a list of 'void ()*'s, so all of the functions are
bitcast to that. However, the dyn_cast doesn't automagically look through
bitcasts. Do that for it.

I'll put MachineLICM back before PEI. All my arm/x86 benchmarks look good, but buildbots don't like it.

The llc command line options for enabling/disabling passes are local to CodeGen/Passes.cpp. This patch associates those options with standard pass IDs so they work regardless of how the target configures the passes.

A target has two ways of overriding standard passes:
1) Redefine the pass pipeline (override TargetPassConfig::add%Stage)
2) Replace or suppress individiual passes with TargetPassConfig::substitutePass.

In both cases, the command line options associated with the pass override the target default.

For example, say a target wants to disable machine instruction scheduling by default:

- The target calls disablePass(MachineSchedulerID) but otherwise does not override any TargetPassConfig methods.

- Without any llc options, no scheduler is run.

- With -enable-misched, the standard machine scheduler is run and honors the -misched=... flag to select the scheduler variant, which may be used for performance evaluation or testing.

Sorry overridePass is ugly. I haven't thought of a better way without replacing the cl::opt framework. I hope to do that one day...

I haven't figured out why CodeGen uses char& for pass IDs. AnalysisID is much easier to use and less bug prone. I'm using it wherever I can for internal implementation. Maybe later we can change the global pass ID definitions as well.

llvm-svn: 150563

Added TargetPassConfig::disablePass/substitutePass as a general mechanism to override specific passes.

expression is referenced, defined, then referenced again, make sure we
instantiate it the second time it's referenced. This is the static data member
analogue of r150518.
