MIPS16/GAS: Relax 32-bit non-PIC PC-relative synthetic instructions Implement the relaxation of MIPS16 PC-relative synthetic LA, DLA, LW and LD instructions to an equivalent sequence of instructions produced where the address operand requested is out of range, absolute or requires linker relocation, for ABIs that use 32-bit addressing and non-PIC code. The sequence generated uses the register specified for the destination operand as a temporary and begins with LI to load the high 16-bit part of the address, then continues with SLL by 16 bits to move that part into place and finally completes with a suitable operation corresponding to the synthetic instruction used, one of: 2-argument ADDIU, 2-argument DADDIU, absolute LW, and absolute LD respectively, providing the low 16-bit part of the address. All instructions use the extended encoding. As a special exception accept absolute addresses for relaxation even in PIC code. For example: la $2, 0x12345678 produces code as: li $2, 0x1234 sll $2, $2, 16 addiu $2, 0x5678 would. Where linker relocation is required emit an R_MIPS16_HI16 relocation on the initial LI instruction and an R_MIPS16_LO16 relocation on the final operation. For example (where `foo' is not local): lw $3, foo produces code as: li $3, %hi(foo) sll $3, $3, 16 lw $3, %lo(foo)($3) would. Emit assembly warnings as appropriate where this new relaxation triggers in the `nomacro' mode or for an instruction manually placed in a branch delay slot in the `noreorder' mode. Refrain from relaxation where an explicit instruction size suffix has been used and in the `noautoextend' mode. gas/ * config/tc-mips.c (RELAX_MIPS16_ENCODE): Add `pic', `sym32' and `nomacro' flags.

MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement Similarly to commit 86b24e15c45b ("MIPS/LD/testsuite: Correct comm-data.exp test ABI/emul/endian arrangement") update the mips-elf.exp test script to: - correctly select emulations for targets using non-traditional MIPS emulations, - correctly select ABIs for targets that do not support all of them, - use the default endianness selection where possible to benefit targets that support only one, - simplify test invocation by providing ABI-specific `run_dump_test' wrappers, specifically `run_dump_test_o32', `run_dump_test_n32', `run_dump_test_n64' and `run_dump_test_eabi', which remove the need to use conditionals across the Expect script or to repeat ABI-specific GAS and LD flags with each invocation, removing numerous test failures for `mips-sgi-irix6', `mips64-openbsd', `mips64el-openbsd' and `mips64el-ps2-elf' targets and broadening coverage for several MIPS targets. There are some new failures for the `mips64el-ps2-elf' target with tests that were not previously run for that target: FAIL: MIPS16 link branch to absolute expression (n32) FAIL: MIPS16 link branch to absolute expression 1 (n32) FAIL: MIPS16 link branch to absolute expression 2 (n32) FAIL: microMIPS link branch to absolute expression (n32) FAIL: MIPS ELF got reloc n32 FAIL: MIPS ELF xgot reloc n32 FAIL: undefined weak symbol overflow (n32) FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs n32 FAIL: ld-mips-elf/attr-gnu-4-0-n32-ph FAIL: ld-mips-elf/attr-gnu-4-1-n32-ph FAIL: ld-mips-elf/attr-gnu-4-2-n32-ph FAIL: ld-mips-elf/attr-gnu-4-3-n32-ph FAIL: MIPSr6 JALR reloc unaligned/cross-mode link test (n32) which are mostly due to dump discrepancies caused by mapping differences coming from the default linker scripts used by these test cases, or sometimes because of the specific MIPS processor architecture recorded in the ELF file taking precedence over the general MIPS ISA level also recorded. Finally, the R_MIPS16_HI16/R_MIPS16_LO16 relocation test failure is a preexisting issue with the IRIX style emulation. These failures will have to be addressed separately. ld/ * testsuite/ld-mips-elf/mips-elf.exp (run_dump_test_abi) (run_dump_test_o32, run_dump_test_n32, run_dump_test_n64) (run_dump_test_eabi): New procedures.

MIPS16/GAS: Relax 32-bit non-PIC PC-relative synthetic instructions Implement the relaxation of MIPS16 PC-relative synthetic LA, DLA, LW and LD instructions to an equivalent sequence of instructions produced where the address operand requested is out of range, absolute or requires linker relocation, for ABIs that use 32-bit addressing and non-PIC code. The sequence generated uses the register specified for the destination operand as a temporary and begins with LI to load the high 16-bit part of the address, then continues with SLL by 16 bits to move that part into place and finally completes with a suitable operation corresponding to the synthetic instruction used, one of: 2-argument ADDIU, 2-argument DADDIU, absolute LW, and absolute LD respectively, providing the low 16-bit part of the address. All instructions use the extended encoding. As a special exception accept absolute addresses for relaxation even in PIC code. For example: la $2, 0x12345678 produces code as: li $2, 0x1234 sll $2, $2, 16 addiu $2, 0x5678 would. Where linker relocation is required emit an R_MIPS16_HI16 relocation on the initial LI instruction and an R_MIPS16_LO16 relocation on the final operation. For example (where `foo' is not local): lw $3, foo produces code as: li $3, %hi(foo) sll $3, $3, 16 lw $3, %lo(foo)($3) would. Emit assembly warnings as appropriate where this new relaxation triggers in the `nomacro' mode or for an instruction manually placed in a branch delay slot in the `noreorder' mode. Refrain from relaxation where an explicit instruction size suffix has been used and in the `noautoextend' mode. gas/ * config/tc-mips.c (RELAX_MIPS16_ENCODE): Add `pic', `sym32' and `nomacro' flags.
