Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:
2. "make profile" doesn't work. It aborts when building host-tools for embedded targets. I didn't yet have enough time to fix this problem. AFAIS this problem is related to handling of LDFLAGS_PROFILE[|_V] in gcc.cfg.in. For host applications, we use gcc for linking host applications, too. With profiling enabled CFLAGS_PROFILE_V contains -pg and is used to compile, but LDFLAGS_PROFILE_V is empty, hence -pg will not be passed to the linker causing gcc to fail to link, because it can't resolve some symbols introduced by compiling with -pg. I am not sure if I can provide a patch for this - Ether it is trivial to fix or requires basic work on host configuration ;- Fixing this one was trivial - But hard to trace. LDFLAGS_PROFILE_V needs to contain the same flags as CFLAGS_PROFILE_V, if gcc is used for linking (What else should have been expected ?, :-). The same problem was present for *_DEBUG_V, but apparently wasn't noticed by anybody, because things didn't break, but were silently ignored. I fixed these problems by setting these flags in configure.in whenever gcc is reported to be the host-compiler. For non-gcc host compilers "make debug" and "make profile" now becomes the same as an ordinary "make". This is a hack and addressing this problen could be more sophisticated, but I don't think it gives much sense to support compile variants for any host program (Who will ever try to profile/debug host tools?). Therefore I don't think it's useful to invest more effort into this problem.
