Subject: Add CMake option DXC_CODEGEN_EXCEPTIONS_TRAP (#6764)
|
||||
|
||||
When enabled, any hlsl::Exception thrown during code generation and
|
||||
optimization will cause the process to trap.
|
||||
|
||||
Bug: 346618785

||||
Change-Id: I9ac966d339ec3090e3455d51a9d7516cc5a3f153

||||
|
||||
HLMatrixLower: allow exceptions to propagate out (#6710)
|
||||
|
||||
If an exception is thrown, don't block it in the TempOverloadPool
|
||||
destructor. Allow it to propagate out as a user-visible error.
|
||||
|
||||
Explicitly clear the TempOverloadPool before returning from the
|
||||
HLMatrixLowerPass::runOnModule. In the normal case, when no exception is
|
||||
thrown, that will still verify that all the overloads actually have been
|
||||
lowered, and will assert out if they aren't.
