configure.in: Added support for a number of optimization options to gcc and other cc compilers. With gcc: On all CPUs: -O2 and -funroll-loops are tried On sparclite (sun4c): -msparclite On microsparc (sun4m): -mv8 On supersparcs and ultrasparcs (sun4d and sun4u): -msupersparc This is more or less equivavalent to the -native option in many cc compilers. The generated binary will work on all sparcs, but it will be optimized for the sparc it was compiled on. -mv8 gives an speed improvment of about 200% in the image module on a Sparc Station 4, and -msupersparc gives almost 300% on an ultra. There is no support in gcc for ultrasparc native code. If GCC had had v8 as a default sparc-instruction set, this hazzle would not really have been neccesary. It currently uses the v7 set, but there are not all that many v7's out there today. With other compilers: On all CPUs: -O, -fast and -native (for apcc): -XO=5, -Xcallmod=2 sun4m: -Xpipe=micro sun4d and sun4u: -Xpipe=super There is probably a need for more optimization options for other CPUs than sparc.
