Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-06-13T02:14:49+00:00 2025-06-13T02:14:49+00:00 jarcherNV jarcher@nvidia.com 2025-06-13T02:14:49+00:00 urn:sha1:9c8fab83a53c43e345566c35f87c16fe7b815e01 Recent separate debugging support added two new functions which broke backwards compatibility. This change restores the old API and moves the new functions to an IComponentType2 interface which can be used if separate debug files are needed. 2025-06-06T21:30:06+00:00 jarcherNV jarcher@nvidia.com 2025-06-06T21:30:06+00:00 urn:sha1:0d16228ae22fa2e1a00e62dc099eea08da7717fe * Add command line option for separate debug info Add command line arg -separate-debug-info which, if provided, produces both a .spv and a .dbg.spv file. The .dbg.spv file contains full debug info and the .spv file has all debug info stripped out. Also add a DebugBuildIdentifier instruction to store a unique hash in both the output files, so they can be more easily matched together. A matching API is provided to allow using the Slang API to retrieve a base and debug SPIRV as well as the debug build identifier string. 2025-03-20T15:38:46+00:00 cheneym2 acheney@nvidia.com 2025-03-20T15:38:46+00:00 urn:sha1:de6cc94e3b7fa5d1b8eeb53993dbf3ca2cec1cc1 * Add -dump-module command to slangc The new -dump-module command to slangc will load and disassemble a slang module, similar to what would be seen by the -dump-ir command, except that -dump-ir tells slangc to print IR as it performs some compilation command. That is, -dump-ir requires some larger compilation task. -dump-module on the otherhand requires no additional goal and will simply load a module and print its IR to stdout independently from other compilation steps. Its intended purpose is to inspect .slang-module files on disk. It can also be used on .slang files which will be parsed and lowered if slang does not find an associated ".slang-module" version of the module on disk. The compilation API is extended with a new IModule::disassemble() method which retrieves the string representation of the dumped IR.

Add methods to count dependent modules and scrape them for downstream target binaries such that the downstream target binaries are linkabe outside of slang, e.g. via spirv-link or dxc.

Add the test script to run the example and compare the hash code with replaying it. * Check nullptr for out Diagnostics We need to check whether the output Diagnostics is a nullptr, because it's allowed. * Fix the double free pointers * Add triangle example as the new test for record-replay Change the example base to add the offline rendering path because we don't want to display anything when we're in the test mode. This change involves introducing a TestBase that will parse the command line option. It will decide whether we are in the test mode. Disable all the swapchain and windows related creation, instead we will only create one single framebuffer for the render target. * Address comments TODO: In the follow up patches, I will add more tests and integrate the test flow into slang-unit-test.
