* | [Hexagon] New HVX target features. | Sumanth Gundapaneni | 2017-10-18 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | This patch lets the llvm tools handle the new HVX target features that are added by frontend (clang). The target-features are of the form "hvx-length64b" for 64 Byte HVX mode, "hvx-length128b" for 128 Byte mode HVX. "hvx-double" is an alias to "hvx-length128b" and is soon will be deprecated. The hvx version target feature is upgated form "+hvx" to "+hvxv{version_number}. Eg: "+hvxv62" For the correct HVX code generation, the user must use the following target features. For 64B mode: "+hvxv62" "+hvx-length64b" For 128B mode: "+hvxv62" "+hvx-length128b" Clang picks a default length if none is specified. If for some reason, no hvx-length is specified to llvm, the compilation will bail out. There is a corresponding clang patch.

* | [Hexagon] Optimize stack slot spills | Krzysztof Parzyszek | 2016-02-12 | 1 | -0/+80 |
Replace spills to memory with spills to registers, if possible. This applies mostly to predicate registers (both scalar and vector), since they are very limited in number. A spill of a predicate register may happen even if there is a general-purpose register available. In cases like this the stack spill/reload may be eliminated completely. This optimization will consider all stack objects, regardless of where they came from and try to match the live range of the stack slot with a dead range of a register from an appropriate register class. llvm-svn: 260758 |
