Chandler Carruth 273acf3395 Remove the ARM-specific variant of this test. It's already covered by
the ARM build bots, and it adds a weird case to the test suite where
a test uses as inputs files in the parent directory.

Talked about this with Dave on IRC and he's fine with this approach even
though it isn't optimal.

Greg Clayton 824e5a2caa More cleanup to remove the CoreFoundation classes out of mainstream code (CFCMutableDictionary, CFCMutableArray, CFCString, etc). Now it is only used in the Results.cpp file for Apple builds only.

2013-03-22 02:38:49 +00:00
Greg Clayton 880afc5728 Much more cleanup on the performance testing infrastructure:
- Added new abtract Results class to keep CoreFoundation out of the tests. There are many subclasses for different settings:
    Results::Result::Dictionary
    Results::Result::Array
    Results::Result::Unsigned
    Results::Result::Double
    Results::Result::String
- Gauge<T> can now write themselves out via a templatized write to results function:
    template <class T>
    Results::ResultSP GetResult (const char *description, T value);
  
- There are four specializations of this so far:
    template <>
    Results::ResultSP GetResult (const char *description, double value);

    template <>
    Results::ResultSP GetResult (const char *description, uint64_t value);

    template <>
    Results::ResultSP GetResult (const char *description, std::string value);

    template <>
    Results::ResultSP GetResult (const char *description, MemoryStats value);
- Don't emit the virtual memory reading from the task info call as it really doesn't mean much as it includes way too much (shared cache + other stuff we don't have control over)
- Fixed other test cases to build correctly and use the new classes

Chandler Carruth 0a9875abfe Revert r177543: Add timing of the IR parsing code with a new
-time-ir-parsing flag

This breaks the layering of the Support library. We can't add an
implementation side to IRReader because it refers directly to entities
only accessible as part of the IR, AsmParser, and BitcodeReader
libraries. It can only be used in a context where all of those libraries
will be available.

We'll need to find some other way to get this functionality, and
hopefully solve the long-standing layering problem of IRReader.h...

Jack Carter 4f69a0f25d Fix the invalid opcode for Mips branch instructions in the assembler
For mips a branch an 18-bit signed offset (the 16-bit 
offset field shifted left 2 bits) is added to the 
address of the instruction following the branch 
(not the branch itself), in the branch delay slot, 
to form a PC-relative effective target address. 

Previously, the code generator did not perform the 
shift of the immediate branch offset which resulted 
in wrong instruction opcode. This patch fixes the issue.

Douglas Gregor 96efb4a442 <rdar://problem/13479214> Make Clang's <stddef.h> robust against system headers defining size_t/ptrdiff_t/wchar_t.
Clang's <stddef.h> provides definitions for the C standard library
types size_t, ptrdiff_t, and wchar_t. However, the system's C standard
library headers tend to provide the same typedefs, and the two
generally avoid each other using the macros
_SIZE_T/_PTRDIFF_T/_WCHAR_T. With modules, however, we need to see
*all* of the places where these types are defined, so provide the
typedefs (ignoring the macros) when modules are enabled.

Hal Finkel f70c41ea7c Remove the G8RC_NOX0_and_GPRC_NOR0 PPC register class
As Jakob pointed out in his review of r177423, having a shared ZERO
register between the 32- and 64-bit register classes causes this
odd G8RC_NOX0_and_GPRC_NOR0 class to be created. As recommended,
this adds a ZERO8 register which differentiates the 32- and 64-bit
zeros.

No functionality change intended.

Sean Silva cdd21b333a Add TableGen ctags(1) emitter and helper script.
To use this in conjunction with exuberant ctags to generate a single
combined tags file, run tblgen first and then
  $ ctags --append [...]

Since some identifiers have corresponding definitions in C++ code,
it can be useful (if using vim) to also use cscope, and
  :set cscopetagorder=1
so that
  :tag X
will preferentially select the tablegen symbol, while
  :cscope find g X
will always find the C++ symbol.

Bill Wendling 173c71ff3d Always forward 'resume' instructions to the outter landing pad.
How did this ever work?

Basically, if you have a function that's inlined into the caller, it may not
have any 'call' instructions, but any 'resume' instructions it may have should
still be forwarded to the outer (caller's) landing pad. This requires that all
of the 'landingpad' instructions in the callee have their clauses merged with
the caller's outer 'landingpad' instruction (hence the bit of ugly code in the
`forwardResume' method).

Testcase in a follow commit to the test-suite repository.

Sean Callanan 6b200d0b3e Modified the way we report fields of records.
Clang requires them to have complete types, but
we were previously only completing them if they
were of tag or Objective-C object types.

I have implemented a method on the ASTImporter
whose job is to complete a type.  It handles not
only the cases mentioned above, but also array
and atomic types.

The .set directive in the Mips the assembler can be

Hal Finkel 756810fe36 Implement builtin_{setjmp/longjmp} on PPC
This implements SJLJ lowering on PPC, making the Clang functions
__builtin_{setjmp/longjmp} functional on PPC platforms. The implementation
strategy is similar to that on X86, with the exception that a branch-and-link
variant is used to get the right jump address. Credit goes to Bill Schmidt for
suggesting the use of the unconditional bcl form (instead of the regular bl
instruction) to limit return-address-cache pollution.

Benchmarking the speed at -O3 of:

static jmp_buf env_sigill;

void foo() {
                __builtin_longjmp(env_sigill,1);
}

main() {
	...

        for (int i = 0; i < c; ++i) {
                if (__builtin_setjmp(env_sigill)) {
                        goto done;
                } else {
                        foo();
                }

done:;
        }

	...
}

vs. the same code using the libc setjmp/longjmp functions on a P7 shows that
this builtin implementation is ~4x faster with Altivec enabled and ~7.25x
faster with Altivec disabled. This comparison is somewhat unfair because the
libc version must also save/restore the VSX registers which we don't yet
support.

Although there is only one Altivec VRSAVE register, it is a member of

Hal Finkel aa03c03a2d Correct PPC FRAMEADDR lowering using a pseudo-register
The old code used to lower FRAMEADDR tried to replicate the logic in the real
frame-lowering code that determines whether or not the frame pointer (r31) will
be used. When it seemed as through the frame pointer would not be used, the
stack pointer (r1) was used instead. Unfortunately, because the stack size is
not yet known, this does not work. Instead, this change introduces new
always-reserved pseudo-registers (FP and FP8) that are replaced during prologue
insertion with the real frame-pointer register (either r1 or r31).

It is important that this intrinsic always return a valid frame address because
it is used by Clang to store the frame address as part of code generation for
__builtin_setjmp.

NEON is not IEEE 754 compliant, so we should avoid lowering single-precision
floating point operations with NEON unless unsafe-math is turned on. The
equivalent VFP instructions are IEEE 754 compliant, but in some cores they're
much slower, so some archs/OSs might still request it to be on by default,
