2009-04-02Temporary workaround for ppc on ppcmalc
target-ppc/translate.c puts values of type opcode_t into .opcodes section, using GCC extension to do so, and hoping that this will make them appear contiguously and in the source order in the resulting executable. This assumption is not safe and is known to be violated with certain versions of GCC, certain flags passed to it and on certain platforms (gcc 4.3.0, -O and PPC/PPC64 for instance) The workaround consists of adding -fno-unit-at-a-time to the list of GCC command line options while building PPC translate.o on a PPC. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6967 c046a42c-6fe2-441c-8c8c-71466251a162

2009-03-29fix format string warnings in block-qcow2.c (Christoph Hellwig)aliguori
Recent patches added two compiler warnings about the format string usage in qcow_read_extensions. One is printing a uint64_t using %lu which is incorrect on many platforms as it can be a unsigned long long, the second one is printing the result of sizeof as %lu, but it is a size_t so it needs to be printed using %zu.
