-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I require help with some work i've been doing lately on gcc (4.2.1 tree). I have managed to put some code in. Now, for function compilation, i require to invoke the i386 (as of now) backend multiple times and with different switches; one time with 3dnow!, another with mmx, another with sse2. And floating point code will require usage of both 387 and sse. It is intended that multiple archs are passed as part of the -march option. (-m3dnow,sse2,sse3 or -march=k6,nocona or maybe - -march=sse2,sse3) Eventually, some of this code may also get used in the PowerPC backend (one time with AltiVec and one time without).. it is intended that multiple versions of functions would go into the assembly file; The global data segment would be created only once, aligned to targeted instruction sets' requirement for efficient accesses (if mmx and sse, alignment might be 8 bytes than 4). I have started working, but not sure which parts I should be touching by now. Please give me your suggestions. Any help in this regard would be greatly appreciated.
