Summary: Writing to a varying in fragment shader causes runtime
"implmentation error" instead of compiler error
Product: Mesa
Version: CVS
Platform: x86 (IA32)
OS/Version: Windows (All)
Status: NEW
Severity: enhancement
Priority: low
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Hi,
only a minor improvement suggestion this time.
I experimented with writing to a varying in my fragment shader. This is
explicitly forbidden in the spec, but I tried it anyway.
It causes this message at runtime:
Mesa 7.1 implementation error: bad register file in store_vector4(fp)
Please report at bugzilla.freedesktop
Now I realise I'm doing something illegal, but would it be an enhancement to
detect this at compile time as an enhancement? This is what happened when I
tried again under an ATI driver.
Thanks, Pete
