Summary: gcc configure script wrongly detect
TARGET_BIG_ENDIAN_DEFAULT
Product: gcc
Version: 4.5.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gough...@yahoo.com.cn
In the configure script "gcc/config.gcc", around line 733:
arm*-*-linux*) # ARM GNU/Linux with ELF
tm_file="dbxelf.h elfos.h linux.h glibc-stdint.h arm/elf.h
arm/linux-gas.h arm/linux-elf.h"
case $target in
arm*b-*)
tm_defines="${tm_defines} TARGET_BIG_ENDIAN_DEFAULT=1"
;;
esac
tmake_file="${tmake_file} t-linux arm/t-arm"
If $target have the form "arm-tab-linux-gnu", this script will enable
big-endian defaults. But the resulting gcc will, by default, generate
little-endian object files, and pass some big-endian argument to linker.
This might be a common problem in scripts. Should the use of "*" be restricted,
or warned in some important scripts?
