2017-05-15MIPS16/GAS: Improve non-constant operand error diagnosticsMaciej W. Rozycki2-1/+10
Improve operand error diagnostics for non-constant expressions used for a 16-bit immediate, making the message more descriptive and indicating the offending operand, e.g.: foo.s:1: Error: invalid operands `lui $2,foo-bar' will show as: foo.s:1: Error: operand 2 must be constant `lui $2,foo-bar' This case does not currently trigger however, for two reasons. First, for regular MIPS and microMIPS assembly in the case of no match caused by `match_int_operand' here, the function is always called again from `mips_ip' via `match_insns', `match_insn' and then `match_operand' for the same opcode table's entry with `lax_match' set to TRUE, in which case the attempt to match succeeds and no error is issued. Second, in the case of MIPS16 assembly no call to `match_int_operand' is made at all for 16-bit immediates, because such immediates are currently only matched with extensible instructions, and these are handled in `match_mips16_insn' via `match_expression' directly rather than via `match_operand'. This will change for MIPS16 code with MIPS16e2 support introduced, where non-extensible instructions accepting 16-bit immediates will be added, so make the case work well right from the start. gas/ * config/tc-mips.c (match_int_operand): Call `match_not_constant' before returning failure for a non-constant 16-bit immediate conditionally allowed.
2017-05-15MIPS/GAS: Improve bignum operand error diagnosticsMaciej W. Rozycki14-2/+109
Improve bignum operand error diagnostics for cases where a constant would be accepted and report them as range errors, also indicating the offending operand and instruction, e.g.: $ cat bignum.s addiu $2, 0x10000000000000000 break 0x10000000000000000 $ as -o bignum.o bignum.s bignum.s:1: Error: bignum invalid bignum.s:2: Error: operand 1 must be constant `break 0x10000000000000000' $ now show as: $ as -o bignum.o bignum.s bignum.s:1: Error: operand 2 out of range `addiu $2,0x10000000000000000' bignum.s:2: Error: operand 1 out of range `break 0x10000000000000000' $ gas/ * config/tc-mips.c (match_const_int): Call `match_out_of_range' rather than `match_not_constant' for unrelocated operands retrieved as an `O_big' expression.

2017-05-15MIPS16/GAS: Improve non-immediate operand error diagnosticsMaciej W. Rozycki10-40/+189
Improve non-immediate operand error diagnostics for extensible MIPS16 instructions and make it match corresponding regular MIPS and microMIPS handling, e.g: $ cat addiu.s addiu $4, $3, $2 $ as -o addiu.o addiu.s addiu.s: Assembler messages: addiu.s:1: Error: operand 3 must be an immediate expression `addiu $4,$3,$2' $ as -mips16 -o addiu.o addiu.s addiu.s: Assembler messages: addiu.s:1: Error: invalid operands `addiu $4,$3,$2' $ To do so observe that for extensible MIPS16 instructions and a non-PC relative operand this case is handled by an explicit OT_INTEGER check in `match_mips16_insn' returning a failure right away and consequently preventing a call to `match_expression' from being made. As from commit d436c1c2e889 ("Improve error reporting for register expressions"), <https://sourceware.org/ml/binutils/2013-08/msg00134.html>, however the check has become redundant as `match_expression' now only ever returns success for OT_INTEGER argument tokens, and a special case of an OT_CHAR `(' token already handled by `match_mips16_insn' just ahead of the `match_expression' call. Previously it also returned success for OT_REG argument tokens. Let the call to `match_expression' always happen then, yielding the same failure for the affected cases, however with more accurate diagnostics provided by the call making reporting consistent: $ as -mips16 -o addiu.o addiu.s addiu.s: Assembler messages: addiu.s:1: Error: operand 3 must be an immediate expression `addiu $4,$3,$2' $ gas/ * config/tc-mips.c (match_mips16_insn): Remove the explicit OT_INTEGER check before the `match_expression' call. * testsuite/gas/mips/mips16-insn-e.l: Adjust messages. * testsuite/gas/mips/mips16-32@mips16-insn-e.l: Likewise. * testsuite/gas/mips/mips16-64@mips16-insn-e.l: Likewise. * testsuite/gas/mips/mips16e-32@mips16-insn-e.l: Likewise. * testsuite/gas/mips/mips16-reg-error.d: New test. * testsuite/gas/mips/mips16-reg-error.l: New stderr output. * testsuite/gas/mips/mips16-reg-error.s: New test source. * testsuite/gas/mips/mips.exp: Run the new test.
2017-05-15MIPS16/GAS: Improve disallowed relocation operand error diagnosticsMaciej W. Rozycki6-1/+98
Improve disallowed relocation operand error diagnostics for MIPS16 code and make it match corresponding regular MIPS and microMIPS handling, e.g: $ cat sltu.s sltu $2, %lo(foo) $ as -o sltu.o sltu.s sltu.s: Assembler messages: sltu.s:1: Error: operand 2 must be constant `sltu $2,%lo(foo)' $ as -mips16 -o sltu.o sltu.s sltu.s: Assembler messages: sltu.s:1: Error: invalid operands `sltu $2,%lo(foo)' $ To do so call `match_not_constant' from `match_mips16_insn' whenever a disallowed relocation operation has been noticed, like `match_const_int' does, making reporting consistent: $ as -mips16 -o sltu.o sltu.s sltu.s: Assembler messages: sltu.s:1: Error: operand 2 must be constant `sltu $2,%lo(foo)' $ gas/ * config/tc-mips.c (match_mips16_insn): Call `match_not_constant' for a disallowed relocation operation. * testsuite/gas/mips/mips16-reloc-error.d: New test. * testsuite/gas/mips/mips16-reloc-error.l: New stderr output. * testsuite/gas/mips/mips16-reloc-error.s: New test source. * testsuite/gas/mips/mips.exp: Run the new test.

Complement commit 919731affbef ("Add MIPS .module directive") and update the GAS manual to refer to the `.module' rather than `.set' directive in command-line option descriptions, following an observation that unlike `.set' and like the respective command-line option the use of the `.module' directive affects the ISA and ASE flags recorded in the object file produced, and therefore it is `.module' rather than `.set' that corresponds to the respective command-line option. gas/ * doc/as.texinfo (-mips16, -no-mips16): Refer to `.module mips16' rather than `.set mips16'.

2017-05-12MIPS/GAS: Unify GP-relative percent-opsMaciej W. Rozycki6-1/+38
For a reason that is unclear commit d6f165938798 ("Support for MIPS16 HI16/LO16 relocations"), <https://sourceware.org/ml/binutils/2005-02/msg00332.html>, which has added support for the R_MIPS16_GPREL relocation, has spelled its corresponding MIPS16 percent-op as `%gprel', rather than `%gp_rel' which is how its regular MIPS counterpart is spelled. To make assembly code sharing easier between the regular MIPS and the MIPS16 ISA make both percent-op spellings acceptable in both kinds of code now. Parts of this change by Matthew Fortune. gas/ * config/tc-mips.c (mips_percent_op): Add "%gprel".

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.

Complement commit 88a7ef168927 ("MIPS16/GAS: Restore unsupported relocation diagnostics") and also propagate constant expressions, either already reduced from absolute symbol references or created from literals in the first place, used as a PC-relative operand with the MIPS16 LA, LW, DLA and LD synthetic instructions to relaxation, matching the way forward absolute symbol references have been handled as from the commit referred and letting relaxation produce any necessary relocations, if possible, for the absolute value requested to be reproduced at the run time. Call `symbol_append' for any expression symbol created for the purpose of MIPS16 relaxation as with constant expressions now propagated from earlier on such symbols may make it through and have R_MIPS16_PC16_S1 relocations emitted against, and therefore need to appear in the symbol table produced. gas/ * config/tc-mips.c (append_insn): Call `symbol_append' for any expression symbol created for MIPS16 relaxation.

2017-03-22gas: xtensa: make trampolines relaxation work with jumps in slots other than 0Max Filippov2-4/+25
add_jump_to_trampoline assumes that jump instruction is in slot 0, when it's in other slot that results in fixup that references NULL symbol, which results in segfault later in xtensa_make_cached_fixup. Search for the non-NULL symbol in the tc_frag_data.slot_symbols and check that there's exactly one such slot. xtensa_relax_frag for RELAX_TRAMPOLINE reassigns fixup from the original instruction with jump to generated jump in the trampoline frag, but does not fix its fx_r_type or fx_size. That results in "undecodable fix" or "fixup not contained within frag" error messages during relaxation. Fix both these fields. gas/ 2017-03-22 Max Filippov <jcmvbkbc@gmail.com> * config/tc-xtensa.c (xtensa_relax_frag): Change fx_size of the reassigned fixup to size of jump instruction (3) and fx_r_type to BFD_RELOC_XTENSA_SLOT0_OP, as there's only one slot.
