Bug#621420: Misbuilds busybox on ARM
Package: gcc-4.5 Version: 4.5.2-8 Severity: normal Hi See Debian #621137; gcc-4.5 4.5.2-8 misbuilds busybox: r5 is clobbered in tryexec() as gcc believes it doesn't return, but it does. This doesn't happen with Linaro GCC 4.5 or GCC 4.6, but it does happen with plain FSF 4.5.2. I've asked on the Linaro Toolchain ML which patch fixes this: http://lists.linaro.org/pipermail/linaro-toolchain/2011-April/001047.html But I didn't open an upstream ticket as there might be one already. See IRC log below for details. 00:52 < lool> michaelh1: if I remove references to applet_no from the function and call sites (it's unused anyway) the issue goes away 00:52 < lool> michaelh1: it's flagged __unused_param__ 00:53 < lool> michaelh1: So I have ash.o and am looking at a disassembled dump, and I can't figure what to look for 00:53 < michaelh1> lool: do you have a preprocessed version of it? What compiler and build options does the fault occur at? 00:53 < michaelh1> lool: I'm suspicious that you're going from a all-register version to a also-something-on-the-stack by adding the extra parameter. 00:54 < lool> michaelh1: Right now I'm doing this with Debian's gcc-4.5 00:54 < lool> no Linaro patchset 00:55 < lool> I was using it earlier, but the busybox versions I was using were not xbuild friendly, or did not reproduce 00:55 < lool> Now that I know that this Debian patch triggers it, I might be able to reproduce with Linaro toolchain 00:55 < michaelh1> lool: yip. Can you do a -save-temps run and send me ash.i and ash.s? 00:56 < lool> michaelh1: BTW I can feel how it would have been useful to have "fsf" toolchains in Ubuntu or Debian and Linaro toolchains in Debian :-) 00:56 < michaelh1> lool: yeah, I want to have a plain linaro PPA in the future. Add a plain fsf as well using the same infrastructure.
