The R_ARC_SDA32 is wrongly described as a ME relocation, fix it. Offset the __SDATA_BEGIN__ to take advantage of the signed 9-bit field of the load/store instructions. include/ 2016-07-08 Claudiu Zissulescu <claziss@synopsys.com> * elf/arc-reloc.def (ARC_SDA32): Don't use ME transformation. ld/ 2016-07-08 Claudiu Zissulescu <claziss@synopsys.com> * emulparams/arcelf.sh (SDATA_START_SYMBOLS): Add offset. * testsuite/ld-arc/sda-relocs.dd: New file. * testsuite/ld-arc/sda-relocs.ld: Likewise. * testsuite/ld-arc/sda-relocs.rd: Likewise. * testsuite/ld-arc/sda-relocs.s: Likewise. * testsuite/ld-arc/arc.exp: Add SDA tests.
