Re: how to modify gcc to compile a[b] differently

2015-04-01 Thread Gry Gunvor
The documentation I find online for modifying gcc is rather old. Is there an up to date map of at least where in gcc the different stages occur? Suppose I just want to modify the instruction emitted for the "*" operator. Where is that? Gry On Wed, Apr 1, 2015 at 2:19 AM, Richard Biener wrote:

how to modify gcc to compile a[b] differently

I want to modify gcc 4.9.2 so that array subscripting expressions a[b] generate a new instruction/syscall foo(a, b) (that is, taking a and b as arguments) rather than just being turned into *(a+b). Further, I want accesses into multi-dimensional arrays a[b][c] to turn into foo(a, (b * row_size + c
