2020-11-17Relocatable read-only section support for absolute jump tableHaochen Gui1-2/+20
This patch puts absolute jump tables into a relocatable read-only section if they are on ELF target and relocation is supported. gcc/ChangeLog: * final.c (final_scan_insn_1): Set jump table relocatable as the second argument of targetm.asm_out.function_rodata_section. * output.h (default_function_rodata_section, default_no_function_rodata_section): Add the second argument to the declarations. * target.def (function_rodata_section): Change the doc and add the second argument. * doc/tm.texi: Regenerate. * varasm.c (jumptable_relocatable): Implement. (default_function_rodata_section): Add the second argument and the support for relocatable read only sections. (default_no_function_rodata_section): Add the second argument. (function_mergeable_rodata_prefix): Set the second argument to false. * config/mips/mips.c (mips_function_rodata_section): Add the second arugment and set it to false. * config/s390/s390.c (targetm.asm_out.function_rodata_section): Set the second argument to false. * config/s390/s390.md: Likewise.

2019-09-30Add a function for getting the ABI of a call insn targetRichard Sandiford1-84/+20
This patch replaces get_call_reg_set_usage with insn_callee_abi, which returns the ABI of the target of a call insn. The ABI's full_reg_clobbers corresponds to regs_invalidated_by_call, whereas many callers instead passed call_used_or_fixed_regs, i.e.: (regs_invalidated_by_call | fixed_reg_set) The patch slavishly preserves the "| fixed_reg_set" for these callers; later patches will clean this up. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (insn_callee_abi): New hook.

2019-09-10Replace call_used_reg_set with call_used_or_fixed_regsRichard Sandiford1-2/+2
CALL_USED_REGISTERS and call_used_regs infamously contain all fixed registers (hence the need for CALL_REALLY_USED_REGISTERS etc.). We try to recover from this to some extent with: /* Contains 1 for registers that are set or clobbered by calls. */ /* ??? Ideally, this would be just call_used_regs plus global_regs, but for someone's bright idea to have call_used_regs strictly include fixed_regs. Which leaves us guessing as to the set of fixed_regs that are actually preserved. We know for sure that those associated with the local stack frame are safe, but scant others. */ HARD_REG_SET x_regs_invalidated_by_call; Since global registers are added to fixed_reg_set and call_used_reg_set too, it's always the case that: call_used_reg_set == regs_invalidated_by_call | fixed_reg_set This patch replaces all uses of call_used_reg_set with a new macro call_used_or_fixed_regs to make this clearer. This is part of a series that allows call_used_regs to be what is now call_really_used_regs. It's a purely mechanical replacement; later patches clean up obvious oddities like "call_used_or_fixed_regs & ~fixed_regs". 2019-09-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * hard-reg-set.h (target_hard_regs::x_call_used_reg_set): Delete.

2018-04-30Use char_span for return type of location_get_source_lineDavid Malcolm1-4/+3
location_get_source_line returns a const char * that isn't 0-terminated, writing back a length through an int * param. This is error-prone, as all call-sites have to take into account the lack of 0-termination, and respect the length of the buffer. It's cleaner to bundle together this pointer+length state into a class, so this patch does so, reusing the "char_span" class that I introduced in r250187 (as part of the fix for PR c/81405). The patch also adds assertions to all access to the char_span. gcc/c-family/ChangeLog: * c-format.c (get_corrected_substring): Update for location_get_source_line returning a char_span.

2018-04-10Set insn_last_address in final_1Richard Sandiford1-0/+3
final_1 already sets insn_current_address for each instruction, making it possible to use some of the address functions in final.c during assembly generation. This patch also sets insn_last_address, since as the comment says, we can treat final as a shorten_branches pass that does nothing. It's then possible to use insn_current_reference_address during final as well. This is needed for the aarch64.md definitions of far_branch to work: (set (attr "far_branch") (if_then_else (and (ge (minus (match_dup 2) (pc)) (const_int -1048576)) (lt (minus (match_dup 2) (pc)) (const_int 1048572))) (const_int 0) (const_int 1)))] This value (tested only during final) uses the difference between the INSN_ADDRESSES of operand 2 and insn_current_reference_address to calculate a conservatively-correct estimate of the branch distance. It takes into account the worst-case gap due to alignment, whereas a direct comparison of INSN_ADDRESSES would give an unreliable, optimistic result. 2018-04-10 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * final.c (final_1): Set insn_last_address as well as insn_current_address.

2018-02-09[LVU] Introduce location viewsAlexandre Oliva1-11/+138
This patch introduces an option to enable the generation of location views along with location lists. The exact format depends on the DWARF version: it can be a separate attribute (DW_AT_GNU_locviews) or (DW_LLE_view_pair) entries in DWARF5+ loclists. Line number tables are also affected. If the assembler is found, at compiler build time, to support .loc views, we use them and assembler-computed view labels, otherwise we output compiler-generated line number programs with conservatively-computed view labels. In either case, we output view information next to line number changes when verbose assembly output is requested. This patch requires an LVU patch that modifies the exported API of final_scan_insn. It also expects the entire SFN patchset to be installed first, although SFN is not a requirement for LVU. for include/ChangeLog * dwarf2.def (DW_AT_GNU_locviews): New. * dwarf2.h (enum dwarf_location_list_entry_type): Add DW_LLE_GNU_view_pair.

2017-12-20poly_int: SUBREG_BYTERichard Sandiford1-2/+3
This patch changes SUBREG_BYTE from an int to a poly_int. Since valid SUBREG_BYTEs must be contained within the mode of the SUBREG_REG, the required range is the same as for GET_MODE_SIZE, i.e. unsigned short. The patch therefore uses poly_uint16(_pod) for the SUBREG_BYTE. Using poly_uint16_pod rtx fields requires a new field code ('p'). Since there are no other uses of 'p' besides SUBREG_BYTE, the patch doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE instead. The patch doesn't bother implementing 'p' support for legacy define_peepholes, since none of the remaining ones have subregs in their patterns. As it happened, the rtl documentation used SUBREG as an example of a code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1). Since there's no direct replacement for XINT, and since people should never use it even if there were, the patch changes the example to use INT_LIST instead. The patch also changes subreg-related helper functions so that they too take and return polynomial offsets. This makes the patch quite big, but it's mostly mechanical. The patch generally sticks to existing choices wrt signedness. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi: Update documentation of SUBREG_BYTE.

2017-12-12[SFN] introduce statement frontier notes, still disabledAlexandre Oliva1-18/+71
This patch completes the infrastructure for the introduction of statement frontiers in C-family languages. It brings in all the code remaining code needed to introduce and transform begin stmt trees, gimple stmts, insns and notes, and ultimately use them to generate the is_stmt column in DWARF2+ line number tables/programs, however none of it is activated: the option that would do so will be introduced in a subsequent patch.

2017-12-02final: Improve output for -dp and -fverbose-asmSegher Boessenkool1-7/+15
This improves the assembler output (for -dp and -fverbose-asm) in several ways. It always prints the insn_cost. It does not print "[length = NN]" but "[c=NN l=NN]", to save space. It does not add one to the instruction alternative number (everything else starts counting those at 0, too). And finally, it tries to keep things lined up in columns a bit better. * final.c (output_asm_name): Print insn_cost. Shorten output. Print which_alternative instead of which_alternative + 1.
