Bug ID: 55361
           Summary: Preprocessor does not handle macros used from other
                    macros
           Product: vkd3d
           Version: 1.8
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: hlsl

Attaching a test that currently fails with:

E5005: Identifier "a" is not declared.

Preprocessed function looks like this:

vkd3d:547664:trace:preproc_lexer_parse float4 func ( float4 arg ) 
vkd3d:547664:trace:preproc_lexer_parse { 
vkd3d:547664:trace:preproc_lexer_parse return ( ( a . r ) + arg . b ) ; 
vkd3d:547664:trace:preproc_lexer_parse }

So nested macro is using argument name as is, instead of using actual name that
outer macro was use with.
