Probably you mean gcc-2.95.1 or newer ... gcc-2.95 crashes when tried for SH target, crashes when building Insight on Linux etc. For a SH-target builder the fixed SH3E support (an undefined '__set_fpscr' with egcs-1.1.2/newlib) and the added SH4 support (-m4, -m4-single, -m4single-only) can make gcc-2.95.1 much better than the earlier one (egcs-1.1.2)... The eCOS-1990321 sources for ARM have the config files for thumb-elf, which target gcc-2.95.x don't yet know -- moving the configure-entry and the thumb-elf config files in 'gcc/config/arm' to gcc-2.95.1 sources and building a cross-compiler for the target seemed to work however... No torture tests etc. made, but compiling newlib, libstdc++ etc. with it and running the generated executables in the simulator with Insight-19990823 worked nicely... Ok, the arm-coff, arm-elf and thumb-coff were already supported in gcc-2.95.1, so for just completeness the thumb-elf would be nice... BTW, the libraries under 'elf' (-fno-leading-underscores) and 'normal (-mno-interwork) seemed to be equal size as the 'default' ones (without using these options = it uses them as default), which could hint them being just vain... So I removed these variations from the MULTILIB definitions and removed the libs for them... Any opinions? Cheers, Kai ------ Want more information?
