Error with gcc-4

[pankaj kapila]

I've been working with u-boot 1.1.3 and binutils gcc-3.4.4 (and also previous versions of both) and it works perfectly. I've not managed to make it working with gcc-4.0.0 nor gcc-4.0.1. I'm working with OMAP1610. Initialially I had some compilation errors that I've managed to solved. I've developed several patches to solve the compilation errors for gcc-4. They are all related to deprecated gcc extensions for C (like postincrementing lvalues). I've tested them to compile with gcc-4 and I tested that they work properly with gcc-3.4.4 (so I am quite sure that they work enough). The problem is that with the patches applied it works properly with gcc-3.4.4 and compiles properly with gcc-4.0.0 but the image generated with gcc-3.4.4 works properly, while the one generated with gcc-4.0.0 does not boot at all (nothing comes out from the serial port). I will upload the patches to improve the code of u-boot reworking the C code to avoid using gcc extensions.  Regards pankaj
