Tried it the other way round: - compiled with 2.18.50.0.7. - then changed binutils to 2.18.50.0.8 Works: frv-linux-ld -r -o init/built-in.o init/main.o init/version.o init/mounts.o init/noinitramfs.o Fails: frv-linux-ld -r -o init/mounts.o init/do_mounts.o frv-linux-ld -r -o init/built-in.o init/main.o init/version.o init/mounts.o init/noinitramfs.o I did an "frv-linux-objdump -Dx" on the init/mounts.o files generated with both binutils versions, and the diff is: --- working 2008-07-15 16:34:49.000000000 +0300 +++ broken 2008-07-15 16:34:40.000000000 +0300 architecture: fr450, flags 0x00000011: HAS_RELOC, HAS_SYMS start address 0x00000000 -private flags = 0x800020d: -mcpu=fr450 -mgpr-32 -msoft-float non-pic relocations +private flags = 0x800030d: -mcpu=fr450 -mgpr-32 -msoft-float -fpic non-pic relocations Sections: Idx Name Size VMA LMA File off Algn Is this an ld bug? > Thanks. > > H.J. cu Adrian -- "Is there not promise of rain?" Ling Tan asked suddenly out of the darkness. There had been need of rain for many days. "Only a promise," Lao Er said. Pearl S.
