Bug #: 13991
Summary: powerpc-rtems ld failure [regression]
Product: binutils
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
Created attachment 6348

Test case
This is a test case which demonstrates that something changed with ld between
binutils 2.10.1 and 2.22 which resulted in a number of our BSPs not being able
to do the transform from an ELF file to a compressed binary with a bootloader
header. I have attached an unfortunately large file with the binaries that
generate this failure.
rtems 4.10 - binutils 2.20.1 with patches
rtems 4.11 - binutils 2.22 with no patches
With the same set of binary files to link.
-bash-4.2$ /opt/rtems-4.10/bin/powerpc-rtems4.10-ld -o hello.ralf bootloader.o
--just-symbols=hello.exe -b binary rtems.gz -T ppcboot.lds
-bash-4.2$ /opt/rtems-4.11/bin/powerpc-rtems4.11-ld -o hello.ralf bootloader.o
--just-symbols=hello.exe -b binary rtems.gz -T ppcboot.lds
ppcboot.lds:97: undefined symbol `__rtems_start' referenced in expression
-bash-4.2$ powerpc-rtems4.10-nm -g hello.exe | grep rtems_start
00000000 T __rtems_start
The symbol is there but not found by the reference in ppcboot.lds.
=========================================
These is the RTEMS RPM information so this can be traced to that.
-bash-4.2$ rpm -qf /opt/rtems-4.10/bin/powerpc-rtems4.10-ld
rtems-4.10-powerpc-rtems4.10-binutils-2.20.1-3.fc16.i686
-bash-4.2$ rpm -qf /opt/rtems-4.11/bin/powerpc-rtems4.11-ld
rtems-4.11-powerpc-rtems4.11-binutils-2.22-1.fc16.i686
