From 47b43f8b15ef35c520b9b287fd17ff25e36bfe95 Mon Sep 17 00:00:00 2001 From: Dietrich Geisler Date: Mon, 29 Jun 2020 17:42:12 -0400 Subject: Backend for Multiple Entry Points (#1411) * Backend for Multiple Entry Points Introduces the basic backend on the compiler for zero or more entry points. Entry points have been extended to lists for several functions, with loopFunctions have been extended to take in entry points and indices as appropriate, to allow for multiple entry points once the frontend is expanded. Several functions are currently being assumed to have a single entry point for simplicity and provide a work in progress commit. * Progress on debugging fixes * Tests passing * Refactored emitEntryPoints * Updated lists to be by constant reference * Fixes to formatting * Refactoring updates for the compiler * Fix for compilation errors * Reformatting * More reformatting * Moved struct around to help with compilation Co-authored-by: Tim Foley --- source/slang/slang-ir-link.cpp | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'source/slang/slang-ir-link.cpp') diff --git a/source/slang/slang-ir-link.cpp b/source/slang/slang-ir-link.cpp index f80f97aff..f1f6d4cd4 100644 --- a/source/slang/slang-ir-link.cpp +++ b/source/slang/slang-ir-link.cpp @@ -1346,9 +1346,10 @@ struct IRSpecializationState } }; +// TODO(DG): Generalize to multiple entry points LinkedIR linkIR( BackEndCompileRequest* compileRequest, - Int entryPointIndex, + List entryPointIndices, CodeGenTarget target, TargetProgram* targetProgram) { @@ -1446,7 +1447,11 @@ LinkedIR linkIR( // arguments which might end up affecting the mangled // entry point name. // - auto entryPointMangledName = program->getEntryPointMangledName(entryPointIndex); + // TODO(DG): spot to generalize to multiple entry points + // Note that only stuff referenced by an entry point gets linked here + // Temporary assertion for checkpoint + SLANG_ASSERT(entryPointIndices.getCount() == 1); + auto entryPointMangledName = program->getEntryPointMangledName(entryPointIndices[0]); auto irEntryPoint = specializeIRForEntryPoint(context, entryPointMangledName); // Bindings for global generic parameters are currently represented -- cgit v1.2.3
