Binutils with MCST patches
493ffac5aa
My original implementation for LDI32 pseudo does not conform to the TI ABI. I wrongly documented my TI PRU ELF object files inspection, which got propagated into my binutils implementation. Issue was exposed when running the GCC ABI testsuite against TI toolchain. According to TI ABI, LDI32 must use first LDI instruction to load the MSB 16bits, and second LDI instruction for the LSB 16bits. This patch will break binary compatibility with previously released binutils versions for PRU. Still, I think it is better to fix binutils to conform to the chip vendor ABI. bfd * elf32-pru.c (pru_elf32_do_ldi32_relocate): Make LDI32 relocation conformant to TI ABI. (pru_elf32_relax_section): Likewise. (pru_elf_relax_delete_bytes): Fix offsets for new LDI32 code. * elf32-pru.c (pru_elf32_do_ldi32_relocate): Ignore addend. (pru_elf32_pmem_relocate): Trap - should not get here. (pru_elf32_relocate_section): Add support for REL relocations. (elf_info_to_howto_rel): Enable REL. (elf_backend_may_use_rel_p): Likewise. (elf_backend_may_use_rela_p): Likewise. (elf_backend_default_use_rela_p): Likewise. gas * config/tc-pru.c (md_apply_fix): Make LDI32 relocation conformant to TI ABI. (pru_assemble_arg_i): Likewise. (output_insn_ldi32): Likewise. * testsuite/gas/pru/ldi.d: Update test for the now fixed LDI32. * gas/config/tc-pru.c (pru_assemble_arg_b): Check imm8 operand range. * gas/testsuite/gas/pru/illegal2.l: New test. * gas/testsuite/gas/pru/illegal2.s: New test. * gas/testsuite/gas/pru/pru.exp: Register new illegal2 test. ld * scripttempl/pru.sc: Add LD sections to allow linking TI toolchain object files. * scripttempl/pru.sc: Switch to init_array. * testsuite/ld-pru/ldi32.d: Update LDI32 test to conform to TI ABI. * testsuite/ld-pru/norelax_ldi32-data.d: Likewise. * testsuite/ld-pru/norelax_ldi32-dis.d: Likewise. * testsuite/ld-pru/relax_ldi32-data.d: Likewise. * testsuite/ld-pru/relax_ldi32-dis.d: Likewise. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
