[cfe-dev] clang and #line directives

[Moritz Lenz]

Hash: SHA1

At the moment #line preprocessor directives don't seem to be implemented:

// file foo.c
int main(int argc, char** argv){
#line 70
    printf("Line %d\n", __LINE__);
    return
}

$ ccc foo.c && ./a.out
clang -emit-llvm-bc -x c -o foo.o foo.c
llvm-ld -native -disable-internalize -o a.out foo.o
Line 3

Sadly parrot needs that print out 'Line 70' to work (the build system
has some weird hooks where macro names are associated with line numbers
in generated code).

Are there any plans to add that soonish?
