From: Stefano Stabellini <stefano.stabell...@eu.citrix.com> Currently the Makefile of disas/libvixl appends -I$(SRC_PATH)/disas/libvixl to QEMU_CFLAGS. As a consequence C++ files that #include "utils.h", such as disas/libvixl/a64/instructions-a64.cc, are going to look for utils.h on all the other include paths first.
When building QEMU as part of the Xen make system, another unrelated utils.h file is going to be chosen for inclusion, causing a build failure: In file included from disas/libvixl/a64/instructions-a64.cc:27:0: /qemu/disas/libvixl/a64/instructions-a64.h:88:64: error: 'rawbits_to_float' was not declared in this scope const float kFP32PositiveInfinity = rawbits_to_float(0x7f800000); Fix the problem by prepending (rather than appending) the libvixl include path to QEMU_CFLAGS.
