how to use the uninstalled C & C++ compilers?

2015-03-31 Thread Matthias Klose
In the past (at least it worked for me in 4.9) it was possible to use the uninstalled C & C++ compilers to build another compiler, using the just built compilers. Useful if you want to build e.g. libgccjit in a second step without bootstrapping again. This doesn't seem to work anymore with 5. At

how to modify gcc to compile a[b] differently

2015-03-31 Thread Gry Gunvor
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
