GCC 4.8.0 (trunk) fails to bootstrap on Fedora 18 ARM (hardfloats)

GCC 4.8.0 (trunk) fails to bootstrap on Fedora 18 ARM (hardfloats)

[David Abdurachmanov]

Hi,

Before actually filling a bug report, I would like to share some detail on mailing-list.

OS: Fedora 18 ARM (ODROID-U2, hardfloats system)
System compiler gcc (GCC) 4.7.2 20121109 (Red Hat 4.7.2-8)
Host/Build triplet: armv7hl-redhat-linux-gnueabi

$ rpm --eval '%{_host} %{_build}'
armv7hl-redhat-linux-gnueabi armv7hl-redhat-linux-gnueabi

Tried compiling CC 4.8.0 r196126 yet bootstrap failed [BOOT_FAIL].

$ cat /usr/include/gnu/stubs.h
/* This file is automatically generated.
   This file selects the right generated file of `__stub_FUNCTION' macros
   based on the architecture being compiled for.  */


#if !defined __ARM_PCS_VFP
# include <gnu/stubs-soft.h>
#endif
#if defined __ARM_PCS_VFP
# include <gnu/stubs-hard.h>
#endif

Well on hardfloat system shouldn't compiler define __ARM_PCS_VFP? There is no gnu/stubs-soft.h on hardfloat system.

The system C pre-processor defines it:

$ cpp -dM -E - < /dev/null | grep -i ARM
#define __ARMEL__ 1
#define __ARM_FEATURE_UNALIGNED 1
#define __ARM_PCS_VFP 1
#define __arm__ 1
#define __ARM_ARCH_7A__ 1
#define __ARM_EABI__ 1
#define __ARM_FEATURE_DSP 1

Quick googling suggest similar issues was in LLVM/Clang:

- https://github.com/archlinuxarm/PKGBUILDs/issues/255
- http://llvm.org/bugs/show_bug.cgi?id=13796

Any suggestions?
