| 2021-03-12 | aix: implement TLS relocation for gas and ld | Clément Chigot | 1 | -1/+29 | |
| Add support for TLS in XCOFF. Amongst the things done by this commit: - Update XCOFF auxialiary header to match new version and allow TLS sections. - Add TLS sections (.tdata and .tbss) support in gas and ld. - Add support for the TLS relocations in gas and ld. Two different types BFD_RELOC are created for PPC and PPC64 as the size is a pointer, thus distinct in 32 or 64bit. The addresses given by ld to .tdata and .tbss is a bit special. In XCOFF, these addresses are actually offsets from the TLS pointer computed at runtime. AIX assembly and linker does the same. In top of that, the .tdata must be before .data (this is mandatory for AIX loader). Thus, the aix ld script is recomputing "." before .data to restore its original value. There might be a simpler way, but this one is working. Optimisation linked to TLS relocations aren't yet implemented. bfd/ * reloc.c (BFD_RELOC_PPC_TLS_LE, BFD_RELOC_PPC_TLS_IE, BFD_RELOC_PPC_TLS_M, BFD_RELOC_PPC_TLS_ML, BFD_RELOC_PPC64_TLS_GD, BFD_RELOC_PPC64_TLS_LD, BFD_RELOC_PPC64_TLS_LE, BFD_RELOC_PPC64_TLS_IE, BFD_RELOC_PPC64_TLS_M, BFD_RELOC_PPC64_TLS_ML): New relocations. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * coff-rs6000.c (xcoff_calculate_relocation): Call xcoff_reloc_type_tls for TLS relocations.

| 2021-03-12 | aix: implement R_TOCU and R_TOCL relocations | Clément Chigot | 1 | -0/+1 | |
| Implement support for largetoc on XCOFF. R_TOCU and R_TOCL are referenced by the new BFD defines: BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO. A new toc storage class is added XMC_TE. In order to correctly handle R_TOCU, the logic behind xcoff_reloc_type_toc is changed to compute the whole TOC offset instead of just the difference between the "link" offset and the "assembly" offset. In gas, add a function to transform addis format used by AIX "addis RT, D(RA)" into the ELF format "addis RT, RA, SI". bfd/ * reloc.c (BFD_RELOC_PPC_TOC16_HI, BFD_RELOC_PPC_TOC16_LO): New relocations. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * coff-rs6000.c (xcoff_calculate_relocation): Call xcoff_reloc_type_toc for R_TOCU and R_TOCL.
