* Support stage_switch. * Update proposal status. * Fix gl_InstanceID. * Fix.
2025-02-05Feature/initialize list side branch (#6058)kaizhangNV
* SP004: implement initialize list translation to ctor - We synthesize a member-wise constructor for each struct follow the rules described in SP004. - Add logic to translate the initialize list to constructor invoke - Add cuda-host decoration for the synthesized constructor - Remove the default constructor when we have a valid member init constructor - Disable -zero-initialize option, will re-implement it in followup (#6109). - Fix the overload lookup issue When creating invoke expression for ctor, we need to call ResolveInvoke() to find us the best candidates, however the existing lookup logic could find us the base constructor for child struct, we should eliminate this case by providing the LookupOptions::IgnoreInheritance to lookup, this requires us to create a subcontext on SemanticsVisitor to indicate that we only want to use this option on looking the constructor. - Do not implicit initialize a struct that doesn't have explicit default constructor.

2025-01-29Fix the type coerce issue (#6215)kaizhangNV
* Fix the type coerce issue When synthesize the default ctor, if there is a base type we will synthesize an InvokeExpr to call base type's default ctor as well. But we should use the type of the inheritanceDecl instead of base struct decl.

2025-01-07Use disassemble API from SPIRV-Tools (#6001)Jay Kwak
* Use disassemble API from SPIRV-Tools This commit uses C API version of SPIRV disassemble function rather than calling spirv-dis.exe. This allows us to use a correct version of SPIRV disassble function that Slangc.exe is using. The implementation is mostly copied from external/spirv-tools/tools/dis/dis.cpp, which is a source file for building spirv-dis.exe. This commit also includes a fix for a bug in RPC communication to `test-server`. When an RPC connection to `test-server.exe` is reused and the second test abruptly fails due to a compile error or SPIRV validation error, the output from the first test run was incorrectly reused as the output for the second test. This commit resets the RPC result before waiting for the response so that even when the RPC connection is erratically disconnected, the result from the previous run will not be reused incorrectly. Some of the tests appear to be relying on this type of behavior. By using an option, `-skip-spirv-validation`, the RPC connection will continue without an interruption.
