* Speed up locview resolution with relaxable fragsAlexandre Oliva2019-04-254-1/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Targets such as xtensa incur a much higher overhead to resolve location view numbers than e.g. x86, because the expressions used to compute view numbers cannot be resolved soon enough. Each view number is computed by incrementing the previous view, if they are both at the same address, or by resetting it to zero otherwise. If PV is the previous view number, PL is its location, and NL is the location of the next view, its number is computed by evaluating NV = !(NL > PL) * (PV + 1). set_or_check_view uses resolve_expression to decide whether portions of this expression can be simplified to constants. The (NL > PL) subexpression is one that can often be resolved to a constant, breaking chains of view number computations at instructions of nonzero length, but not after alignment that might be unnecessary. Alas, when nearly every frag ends with a relaxable instruction, frag_offset_fixed_p will correctly fail to determine a known offset between two unresolved addresses in neighboring frags, so the unresolved symbolic operation will be constructed and used in the computation of most view numbers. This results in very deep expressions. As view numbers get referenced in location view lists, each operand in the list goes through symbol_clone_if_forward_ref, which recurses on every subexpression. If each view number were to be referenced, this would exhibit O(n^2) behavior, where n is the depth of the view number expressions, i.e., the length of view number sequences without an early resolution that cuts the expression short. This patch enables address compares used by view numbering to be resolved even when exact offsets are not known, using new logic to determine when the location either remained the same or changed for sure, even with the possibility of relaxation. This enables most view number expressions to be resolved with a small, reasonable depth.

* resolve_symbol_value vs. .loc view resolutionAlan Modra2019-04-243-29/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In most cases we don't want expression symbols, such as that created for an expression like "symbol + (1f - .)", resolved down to a constant. Instead we'd like to leave the expression as "symbol + constant" once the "1f - ." part has been resolved, and let the backend decide whether "symbol" can be reduced further. However, that doesn't work when trying to resolve .loc view symbols early. We get expression symbols left as an O_symbol expression pointing at an absolute symbol, and marked as sy_flags.sy_resolved. That wouldn't really be a problem, but when one of those expression symbols is used in further .loc view expressions, its value is taken as zero. This patch fixes the symbol value mistake, and stops creation of O_symbol expression symbols pointing to absolute symbols. Either of these fixes would cure the .loc view usage. PR 24444 * symbols.c (resolve_symbol_value): When handling symbols marked as sy_flags.resolved, return correct value for the case of expression symbols left as an O_symbol expression. Merge O_symbol code handling undefined and common symbols with code handling special cases of expression symbols. Use seg_left to test for undefined and common symbols. Don't leave an O_symbol expression when X_add_symbol resolves to the absolute_section. Init final_val later. * testsuite/gas/mmix/basep-7.d: Adjust expected output.

* [binutils, ARM, 16/16] Add support to VLDR and VSTR of system registersAndre Vieira2019-04-156-4/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GNU as' Arm backend assumes each mnemonic has a single entry in the instruction table but VLDR (system register) and VSTR (system register) are different instructions than VLDR and VSTR. It is thus necessary to add some form of demultiplexing in the parser. It starts by creating a new operand type OP_VLDR which indicate that the operand is either the existing OP_RVSD operand or a system register. The function parse_operands () then tries these two cases in order, calling the new parse_sys_vldr_vstr for the second case. Since the encoding function is specified in the instruction table entry, it also need to have some sort of demultiplexing. This is done in do_vldr_vstr which either calls the existing do_neon_ldr_str () or calls the new do_t_vldr_vstr_sysreg (). A new internal relocation is needed as well since the offset has a shorter range than in other Thumb coprocessor instructions. Disassembly also requires special care since VSTR (system register) reuse the STC encoding with the coprocessor number 15. Armv8.1-M Mainline ARM manual states that coprocessor 8, 14 and 15 are reserved for floating-point and MVE instructions a feature bit check is added if the coprocessor number is one of this value and we are trying to match a coprocessor instruction (eg. STC) to forbid the match.

* [binutils, ARM, 15/16] Add support for VSCCLRMAndre Vieira2019-04-156-14/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Like for CLRM, this patch aims to share as much logic with the similar looking VLDM/VSTM. This is achieved by adding 2 new enumerator values in enum reg_list_els for the single-precision and double-precision variants of VSCCLRM and extending parse_vfp_reg_list () to deal with these types. These behave like the existing REGLIST_VFP_S and REGLIST_VFP_D types with extra logic to expect VPR as the last element in the register list. The function is algo augmented with a new partial_match parameter to indicate if any register other than VPR had already been parsed in the register list so as to not try parsing the second variant if that's the case and return the right error message. The rest of the patch is the usual encoding function, new disassembler table entries and format specifier and parsing, encoding and disassembling tests. It is worth mentioning that the new entry in the disassembler table was added in the coprocessor-related table despite VSCCLRM always being available even in FPU-less configurations. The main reason for this is that VSCCLRM also match VLDMIA entry and must thus be tried first but coprocessor entries are tried before T32 entries. It also makes sense because it is in the same encoding space as coprocessor and VFP instructions and is thus the natural place for someone to look for this instruction. Note: Both variants of VSCCLRM support D16-D31 registers but Armv8.1-M Mainline overall does not. I have thus decided not to implement support for these registers in order to keep the code simpler. It can always be added later if needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given the similarity between LDM/STM and CLRM register lists, most of the changes in this patch aim at sharing code between those two sets of instruction. Sharing is achieved both in parsing and encoding of those instructions. In terms of parsing, parse_reg_list () is extended to take a type that describe what type of instruction is being parsed. The reg_list_els used for parse_vfp_reg_list () is reused for the type and that function is added an assert for the new REGLIST_CLRM and REGLIST_RN enumerators. parse_reg_list () is then taught to accept APSR and reject SP and PC when parsing for a CLRM instruction. At last, caller of parse_reg_list () is updated accordingly and logic is added for the new OP_CLRMLST operand. Encoding-wise, encode_thumb2_ldmstm () is reused to encode the variable bits of CLRM and is thus renamed encode_thumb2_multi (). A new do_io parameter is added to distinguish between LDM/STM and CLRM which guard all the LDM/STM specific code of the function. Finally objdump is told how to disassemble CLRM, again reusing the logic to print the LDM/STM register list (format specifier 'm'). Tests are also added in the form of negative tests to check parsing and encoding/disassembling tests.

* Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86Rainer Orth2019-04-1021-0/+426
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix H.J. implemented for PR gas/22791 in the thread starting at [PATCH] x86-64: Treat PC32 relocation with branch as PLT32 https://sourceware.org/ml/binutils/2018-02/msg00065.html is causing problems on Solaris/x86. The native linker is strongly preferred there, and there's no intention of implementing the linker optimization he plans there. Besides, the kernel runtime linker, otherwise has no need to deal with that reloc at all, and instead of adding (possibly even more) workarounds with no benefit, it seems appropriate to disable the R_X86_64_PLT32 generation as branch marker on Solaris/x86 in the first place. The patch itself is trivial, the only complication is adapting the testsuite. Since I've found no way to have conditional sections in the .d files, I've instead used the solution already found elsewhere of having separate .d files for the affected tests in an i386/solaris subdirectory and skipping the original ones.

* [GAS, Arm] CLI with architecture sensitive extensionsAndre Vieira2019-04-0141-46/+2843
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new framework to add architecture sensitive extensions, like GCC does. This patch also implements all architecture extensions currently available in GCC. This framework works as follows. To enable architecture sensitive extensions for a particular architecture, that architecture must contain an ARM_ARCH_OPT2 entry in the 'arm_archs' table. All fields here are the same as previous, with the addition of a new extra field at the end to <name> it's extension table. This <name>, corresponds to a <name>_ext_table of type 'struct arm_ext_table'. This struct can be filled with three types of entries: ARM_ADD (string <ext>, arm_feature_set <enable_bits>), which means +<ext> will enable <enable_bits> ARM_REMOVE (string <ext>, arm_feature_set <disable_bits>), which means +no<ext> will disable <disable_bits> ARM_EXT (string <ext>, arm_feature_set <enable_bits>, arm_feature_set <disable_bits>), which means +<ext> will enable <enable_bits> and +no<ext> will disable <disable_bits> (this is to be used instead of adding an ARM_ADD and ARM_REMOVE for the same <ext>) This patch does not disable the use of the old extensions, even if some of them are duplicated in the new tables. This is a "in-between-step" as we may want to deprecate the old table of extensions in later patches. For now, GAS will first look for the +<ext> or +no<ext> in the new table and if no entry is found it will continue searching in the old table, following old behaviour. If only an ARM_ADD or an ARM_REMOVE is defined for <ext> and +no<ext> or +<ext> resp. is used then it also continues to search the old table for it. A couple of caveats: - This patch does not enable the use of these architecture extensions with the '.arch_extension' directive. This is future work that I will tend to later. - This patch does not enable the use of these architecture extensions with the -mcpu option. This is future work that I will tend to later. - This patch does not change the current behaviour when combining an architecture extension and using -mfpu on the command-line. The current behaviour of GAS is to stage the union of feature bits enabled by both -march and -mfpu. GCC behaves differently here, so this is something we may want to revisit on a later date.
