Summary: glibc is unbuildable on an EABI ARMv4 system.
Product: glibc
Version: 2.12
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: ports
AssignedTo: roland@gnu.org
ReportedBy: filip.zyzniewski@gmail.com
I am one of the developers of jlime (http://www.jlime.org). I was
trying to build an userland for the HP Jornada 720 (SA-1110 based
machine) today and I have noticed that it won't build. It fails when
building eglibc with the following error message:

=========================================================
gcc-4.4.2 and binutils-2.18 (or 2.20, I'm not sure) are capable of
creating working EABI executables for ARMv4 processors. THUMB mode
instructions in the file above cause (e)glibc to be unbuildable in
this configuration.
I've tracked this file down
http://repo.or.cz/w/glibc-ports.git/commitdiff/2dcd7ed8fd149a5aefc8c7a7ff041ff389348b4f
and here I am :).

I think it should be OK to condition the entire contents of
libc-do-syscall.S on #ifdef __thumb__; this hidden function is only used
when building glibc as Thumb.

I get the same problem with:
armeb-unknown-linux-gnueabi -march=armv5 -mtune=xscale -mno-thumb
And applying the above patch works for me.

Ignore my previous note.
-march=armv5 -mtune=xscale
produces bad binaries for xscale.
./hello
Illegal instruction
building with -mcpu=xscale (no -march or -mtune) does not need this patch.
