[Bug pch/40715] New: SPU compiler does not work properly with precompiled headers

[ryan dot sammartino at gmail dot com]

The SPU compiler does not work properly with precompiled headers.

$ cat pch.h
#include <spu_intrinsics.h>

$ cat test.cpp
vec_float4 add(vec_float4 a, vec_float4 b)
{
        return spu_add(a, b);
}

$ /opt/cell/toolchain/bin/spu-g++ -O3 pch.h -o pch.h.gch

$ /opt/cell/toolchain/bin/spu-g++ -O3 -include pch.h -S test.cpp
test.cpp: In function 'float __vector__ add(float __vector__, float
__vector__)':
test.cpp:3: error: insufficient arguments to overloaded function spu_add
test.cpp:4: confused by earlier errors, bailing out


However, if I delete pch.h.gch:

$ rm -f pch.h.gch
$ /opt/cell/toolchain/bin/spu-g++ -O3 -include pch.h -S test.cpp

it compiles as expected.

This behaviour is observed in:

$ /opt/cell/toolchain/bin/spu-g++ -v

This was fixed in 4.5.0 I think.
