libclc: Make all built-ins overloadable The SPIR spec states that all OpenCL built-in functions should be overloadable and mangled, to ensure consistency. Add the overload attribute to functions which were missing them: work dimensions, memory barriers and fences, and events.

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636 | 7 年前 | |

Add ADDR_SPACE parameter to _CLC_V_V_VP_VECTORIZE This macro is currently unused, but I plan to use it shortly. The previous form did casts of pointers without an address space, which doesn't work so well for CL 1.x.

libclc: Fix rounding during type conversion The rounding during type conversion uses multiple conversions, selecting between them to try to discover if rounding occurred. This appears to not have been tested, since it would generate code of the form: float convert_float_rtp(char x) { float r = convert_float(x); char y = convert_char(y); [...] } which will access uninitialised data. The idea appears to have been to have done a char -> float -> char roundtrip in order to discover the rounding, so do this. Discovered by inspection.

configure: Add --enable-runtime-subnormal option This makes it possible for runtime implementations to disable subnormal handling at runtime. When this flag is enabled, decisions about how to handle subnormals in the library will be controlled by an external variable called __CLC_SUBNORMAL_DISABLE. Function implementations should use these new helpers for querying subnormal support: __clc_fp16_subnormals_supported(); __clc_fp32_subnormals_supported(); __clc_fp64_subnormals_supported(); In order for the library to link correctly with this feature, users will be required to either: 1. Insert this variable into the module (if using the LLVM/Clang C++/C APIs). 2. Pass either subnormal_disable.bc or subnormal_use_default.bc to the linker. These files are distributed with liblclc and installed to $(installdir). e.g.: llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_disable.bc or llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_use_default.bc If you do not supply the --enable-runtime-subnormal then the library behaves the same as it did before this commit. In addition to these changes, the patch adds helper functions that should be used when implementing library functions that need special handling for denormals: __clc_fp16_subnormals_supported(); __clc_fp32_subnormals_supported(); __clc_fp64_subnormals_supported(); llvm-svn: 235329 | 11 年前 | |
