We have a software tree that we compile for Solaris Sparc and Linux X86. There are several versions this software that we support, 4.5.3 and 4.7 are still our current versions. We compile up 4.5.3 for Solaris and Linux with gcc-295. 4.7 is compiled with gcc-32.
The problem that we're seeing is this: 4.5.3 and 4.7 run almost the same speed on Linux. However, on Solaris Sparc 4.5.3 runs about 10x faster than the Linux version. All the compile lines and complier options are the same (and quoted at the bottom of this message).
Can someone shed some light on to why me might be seeing this problem? The compile line that I pasted is from our Linux build. The only differences between Solaris and Linux is the -mtune=ultrasparc and -mcpu-v8 options on Sparc.
Any ideas???
