* R600/SI: Only create one instruction when spilling/restoring register v3Tom Stellard2014-05-021-9/+48
| | | | | | | | | | | | | | | | | | The register spiller assumes that only one new instruction is created when spilling and restoring registers, so we need to emit pseudo instructions for vector register spills and lower them after register allocation. v2: - Fix calculation of lane index - Extend VGPR liveness to end of program. v3: - Use SIMM16 field of S_NOP to specify multiple NOPs. https://bugs.freedesktop.org/show_bug.cgi?id=75005 llvm-svn: 207843
* R600/SI: Implement spilling of SGPRs v5Tom Stellard2013-11-271-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | SGPRs are spilled into VGPRs using the {READ,WRITE}LANE_B32 instructions. v2: - Fix encoding of Lane Mask - Use correct register flags, so we don't overwrite the low dword when restoring multi-dword registers. v3: - Register spilling seems to hang the GPU, so replace all shaders that need spilling with a dummy shader. v4: - Fix *LANE definitions - Change destination reg class for 32-bit SMRD instructions v5: - Remove small optimization that was crashing Serious Sam 3. https://bugs.freedesktop.org/show_bug.cgi?id=68224 https://bugs.freedesktop.org/show_bug.cgi?id=71285 NOTE: This is a candidate for the 3.4 branch. llvm-svn: 195880
* [weak vtables] Remove a bunch of weak vtablesJuergen Ributzka2013-11-191-0/+4
| | | | | | | | | | | | This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed. Thanks Alexey for pointing them out. Differential Revision: http://llvm-reviews.chandlerc.com/D2068 Reviewed by Andy llvm-svn: 195064
* Revert r194865 and r194874.Alexey Samsonov2013-11-181-4/+0
| | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. llvm-svn: 194997
