How to keep array type info in arguments

Project Infrastructure LLVM Dev List Archives

When I tried LLVM for a function with an array as an argument, the type infomation of the array seems lost. For example, for this function,

void DCT(short data[64], char step, char offset),

its corresponding LLVM code will be

void %DCT8_int(short* %data, sbyte %step, sbyte %offset) ,

and every access of “data” will be a pointer access, instead of an array access.

Is there any way to retrieve the array type infomation back in LLVM?

Nope, sorry. This behavior is mandated by C. If you can hack the code, you should be able to use :

void DCT(short data[1][64], char step, char offset),

which will give you the info you want.
