* Object: Provide a richer means of describing auxiliary symbolsDavid Majnemer2014-03-19
| | | | | | | | | | | | | | | | The current state of affairs has auxiliary symbols described as a big bag of bytes. This is less than satisfying, it detracts from the YAML file as being human readable. Instead, allow for symbols to optionally contain their auxiliary data. This allows us to have a much higher level way of describing things like weak symbols, function definitions and section definitions. This depends on D3105.

* DebugInfo: Use the comp_dir of the referencing type units when building ↵David Blaikie2014-03-19
| | | | | | | | | | | | debug_line.dwo This isn't a complete fix - it falls back to non-comp_dir when multiple compile units are in play. Adding a map of comp_dir to table is part of the more general solution, but I gave up (in the short term) when I realized I'd also have to calculate the size of each type unit so as to produce correct DW_AT_stmt_list attributes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204202 91177308-0d34-0410-b5e6-96231b3b80d8
* Expose "noduplicate" attribute as a property for intrinsics.Eli Bendersky2014-03-18
| | | | | | | | | | | | | | The "noduplicate" function attribute exists to prevent certain optimizations from duplicating calls to the function. This is important on platforms where certain function call duplications are unsafe (for example execution barriers for CUDA and OpenCL). This patch makes it possible to specify intrinsics as "noduplicate" and translates that to the appropriate function attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204200 91177308-0d34-0410-b5e6-96231b3b80d8

* X86 memcpy lowering: use "rep movs" even when esi is used as base pointerHans Wennborg2014-03-18
| | | | | | | | | | | | | For functions where esi is used as base pointer, we would previously fall back from lowering memcpy with "rep movs" because that clobbers esi. With this patch, we just store esi in another physical register, and restore it afterwards. This adds a little bit of register preassure, but the more efficient memcpy should be worth it.

* Fix PR19144: Incorrect offset generated for int-to-fp conversion at -O0.Bill Schmidt2014-03-18
| | | | | | | | | | | | | | | | | | | When converting a signed 32-bit integer to double-precision floating point on hardware without a lfiwax instruction, we have to instead use a lfd followed by fcfid. We were erroneously offsetting the address by 4 bytes in preparation for either a lfiwax or lfiwzx when generating the lfd. This fixes that silly error. This was not caught in the test suite since the conversion tests were run with -mcpu=pwr7, which implies availability of lfiwax. I've added another test case for older hardware that checks the code we expect in the absence of lfiwax and other flavors of fcfid. There are fewer tests in this test case because we punt to DAG selection in more cases on older hardware. (We must generate complex fiddly sequences in those cases, and there is marginal benefit in duplicating that logic in fast-isel.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204155 91177308-0d34-0410-b5e6-96231b3b80d8

* Tolerate unmangled names in sample profiles.Diego Novillo2014-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The compiler does not always generate linkage names. If a function has been inlined and its body elided, its linkage name may not be generated. When the binary executes, the profiler will use its unmangled name when attributing samples. This results in unmangled names in the input profile. We are currently failing hard when this happens. However, in this case all that happens is that we fail to attribute samples to the inlined function. While this means fewer optimization opportunities, it should not cause a compilation failure. This patch accepts all valid function names, regardless of whether they were mangled or not.
