Leverage the method OpenCL uses that adds C intrinsics when the lookup failed. There is no need to define C intrinsics in the header file any more. It could help to avoid the large header file to speed up the compilation of RVV source code. Besides that, only the C intrinsics used by the users will be added into the declaration table. This patch is based on https://reviews.llvm.org/D103228 and inspired by OpenCL implementation. ### Experimental Results #### TL;DR: - Binary size of clang increase ~200k, which is +0.07% for debug build and +0.13% for release build. - Single file compilation speed up ~33x for debug build and ~8.5x for release build - Regression time reduce ~10% (`ninja check-all`, enable all targets) #### Header size change ``` | size | LoC | ------------------------------ Before | 4,434,725 | 69,749 | After | 6,140 | 162 | ``` #### Single File Compilation Time Testcase: ``` #include <riscv_vector.h> vint32m1_t test_vadd_vv_vfloat32m1_t(vint32m1_t op1, vint32m1_t op2, size_t vl) { return vadd(op1, op2, vl); } ``` ##### Debug build: Before: ``` real 0m19.352s user 0m19.252s sys 0m0.092s ``` After: ``` real 0m0.576s user 0m0.552s sys 0m0.024s ``` ~33x speed up for debug build ##### Release build: Before: ``` real 0m0.773s user 0m0.741s sys 0m0.032s ``` After: ``` real 0m0.092s user 0m0.080s sys 0m0.012s ``` ~8.5x speed up for release build #### Regression time Note: the failed case is `tools/llvm-debuginfod-find/debuginfod.test` which is unrelated to this patch. ##### Debug build Before: ``` Testing Time: 1358.38s Skipped : 11 Unsupported : 446 Passed : 75767 Expectedly Failed: 190 Failed : 1 ``` After ``` Testing Time: 1220.29s Skipped : 11 Unsupported : 446 Passed : 75767 Expectedly Failed: 190 Failed : 1 ``` ##### Release build Before: ``` Testing Time: 381.98s Skipped : 12 Unsupported : 1407 Passed : 74765 Expectedly Failed: 176 Failed : 1 ``` After: ``` Testing Time: 346.25s Skipped : 12 Unsupported : 1407 Passed : 74765 Expectedly Failed: 176 Failed : 1 ``` #### Binary size of clang ##### Debug build Before ``` text data bss dec hex filename 335261851 12726004 552812 348540667 14c64efb bin/clang ``` After ``` text data bss dec hex filename 335442803 12798708 552940 348794451 14ca2e53 bin/clang ``` +253K, +0.07% code size ##### Release build Before ``` text data bss dec hex filename 144123975 8374648 483140 152981763 91e5103 bin/clang ``` After ``` text data bss dec hex filename 144255762 8447296 483268 153186326 9217016 bin/clang ``` +204K, +0.13% Authored-by: Kito Cheng <kito.cheng@sifive.com> Co-Authored-by: Hsiangkai Wang <kai.wang@sifive.com> Reviewed By: khchen, aaron.ballman Differential Revision: https://reviews.llvm.org/D111617
