From f12c2552b3f494cbc8245edb90b32b93ca8a1539 Mon Sep 17 00:00:00 2001 From: Tim Foley Date: Mon, 16 Oct 2017 13:12:11 -0700 Subject: Implement notion of a "container format" (#213) The big addition here is that the Slang "bytecode" is no longer treated as just a "code generation target" (`CodeGenTarget`) akin to DX bytecode (DXBC) or SPIR-V, but instead is a `ContainerFormat` that can be used to emit all the results of a compile request (well, currently just the IR-as-BC, but the intention is there). Getting to this goal involved some prior checkins that eliminated bogus "targets" that weren't really akin to SPIR-V or DXBC: `-target slang-ir-asm` and `-target reflection-json`. Those targets were really in place to support testing, and so they've been made more explicit testing/debug options. This change eliminates `-target slang-ir` and instead tries to allow the user to specify `-o foo.slang-module` as an output file name, that indicates the intention to output a "container" file that will wrap up all the generated code. I've also gone ahead and generalized the existing `-target` option so that we are actually building up a *list* of code generation targets. This is largely just a cleanup, since it forces code to be more aware of when it is doing something target-specific vs. target independent. For example, reflection layout information lives on a requested target, and not on the compile request as a whole, and similarly output code is per-target, per-entry-point. As a cleanup, I eliminated support for per-translation-unit output. This was vestigial code from back when I used to try and do HLSL generation for a whole translation unit instead of per-entry-point (which turned out to be a lot of complexity for little gain), and it was only being used in the `hello` example and the `render-test` test fixture - in both cases fixing it up was easy enough. I've stubbed out the old `spGetTranslationUnitSource` API, but haven't removed it yet. --- source/slang/type-layout.cpp | 1 - 1 file changed, 1 deletion(-) (limited to 'source/slang/type-layout.cpp') diff --git a/source/slang/type-layout.cpp b/source/slang/type-layout.cpp index 034982ae4..19b9a435e 100644 --- a/source/slang/type-layout.cpp +++ b/source/slang/type-layout.cpp @@ -621,7 +621,6 @@ LayoutRulesFamilyImpl* GetLayoutRulesFamilyImpl(CodeGenTarget target) case CodeGenTarget::HLSL: case CodeGenTarget::DXBytecode: case CodeGenTarget::DXBytecodeAssembly: - case CodeGenTarget::SlangIR: return &kHLSLLayoutRulesFamilyImpl; case CodeGenTarget::GLSL: -- cgit v1.2.3
