From 4f2330d059ab5943ddf33bfed37be6a0378d43a8 Mon Sep 17 00:00:00 2001 From: kaizhangNV <149626564+kaizhangNV@users.noreply.github.com> Date: Wed, 8 May 2024 09:13:45 -0700 Subject: capture/replay: interface implementation 1 (#4122) * capture/replay: interface implementation 1 - Add global session, filesystem, and session capture interface classes: GlobalSessionCapture for IGlobalSession FileSystemCapture for ISlangFileSystemExt SessionCapture for ISession - Add environment variables to enable it The 2 variables are SLANG_CAPTURE_LAYER and SLANG_CAPTURE_LOG_LEVEL SLANG_CAPTURE_LAYER: In slang_createGlobalSession(), after the compiling/loading stdlib, we will check the capture environment variable, if it's set to 1, we will create a GlobalSessionCapture object and return to user code. SLANG_CAPTURE_LOG_LEVEL: This is to set the log level, user can choose the loglevel to debug. (We can remove this when the feature is fully implemented). - Update premake file and cmake file to add the capture/replay source folder * Fix Windows build error Fix windows build error by adding the "SLANG_MCALL" keyword. Change to use Slang::ComPtr for those captured object pointers to simplify the resource management. Use __func__ macro to print the function name in the log. --- source/slang/slang-api.cpp | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'source/slang/slang-api.cpp') diff --git a/source/slang/slang-api.cpp b/source/slang/slang-api.cpp index 7284f2468..ff37d6398 100644 --- a/source/slang/slang-api.cpp +++ b/source/slang/slang-api.cpp @@ -5,6 +5,8 @@ #include "slang-repro.h" #include "../core/slang-shared-library.h" +#include "../slang-capture-replay/slang-global-session.h" +#include "../slang-capture-replay/capture_utility.h" // implementation of C interface @@ -116,7 +118,18 @@ SLANG_API SlangResult slang_createGlobalSession( } } - *outGlobalSession = globalSession.detach(); + // Check if the SLANG_CAPTURE_ENABLE_ENV is enabled + if (SlangCapture::isCaptureLayerEnabled()) + { + SlangCapture::GlobalSessionCapture* globalSessionCapture = + new SlangCapture::GlobalSessionCapture(globalSession.detach()); + Slang::ComPtr result(globalSessionCapture); + *outGlobalSession = result.detach(); + } + else + { + *outGlobalSession = globalSession.detach(); + } #ifdef SLANG_ENABLE_IR_BREAK_ALLOC // Reset inst debug alloc counter to 0 so IRInsts for user code always starts from 0. -- cgit v1.2.3
