End-to-end shader build through the V2 pipeline:
|
||
|
|
the inner project.cpp registers a vertex shader via cfg.shaders, and
|
||
|
|
crafter.build-lib invokes glslang in-process to lower it to SPIR-V. The
|
||
|
|
test verifies the resulting .spv file lands in the per-target bin dir
|
||
|
|
and starts with the SPIR-V magic word — a zero-length output or one
|
||
|
|
written under a different name would be flagged here rather than
|
||
|
|
silently passing.
