2019-11-28gas/riscv: Produce version 3 DWARF CIE by defaultAndrew Burgess1-0/+11
The flag controlling the default DWARF CIE version to produce now starts with the value -1. This can be modified with the command line flag as before, but after command line flag processing, in md_after_parse_args targets can, if the global still has the value -1, override this value. This gives a target specific default. If a CIE version is not select either by command line flag, or a target specific default, then some new code in dwarf2_init now select a global default. This remains as version 1 to match previous behaviour. This RISC-V has a target specific default of version provided, this make the return column uleb128, which means we can use all DWARF registers include CSRs. I chose to switch to version 3 rather than version 4 as this is most similar to the global default (version 1). Switching to version 4 adds additional columns to the CIE header. gas/ChangeLog: * as.c (flag_dwarf_cie_version): Change initial value to -1, and update comment. * config/tc-riscv.c (riscv_after_parse_args): Set flag_dwarf_cie_version if it has not already been set. * dwarf2dbg.c (dwarf2_init): Initialise flag_dwarf_cie_version if needed. * testsuite/gas/riscv/default-cie-version.d: New file. * testsuite/gas/riscv/default-cie-version.s: New file. ld/ChangeLog: * testsuite/ld-elf/eh5.d: Accept version 3 DWARF CIE.

2019-09-19bfd_section_* macrosAlan Modra1-14/+9
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-05-05[LVu] base subseg head view on prev subseg's tailAlexandre Oliva1-5/+32
Location views at borders between subsegments/subsections in the same segment/section are computed as if each new subsegment/subsection started with a forced view reset to zero, but the line number program does not introduce resets that are not explicitly requested, so if a subsegment ends at the same address another starts, the line number program will have a continuity of views at the border address, whereas the initial view number label in the latter subsegment will be miscomputed as zero. This patch delays the assignment of view expressions at subsegment heads to the time of chaining the frags of subsegments into a single segment, so that they are set based on the view at the end of the previous subsegment in the same segment. The line number program created for the test program had an unnecessary DW_LNS_advance_pc at the end.

2019-03-13dwarf2: Align relocation within .debug_line sectionChristian Eggers1-3/+15
All relocations specify a byte address. As dwarf debug information is organized in octets, some relocations may not be aligned. While it might be possible to define special relocations that operate at an octet offset from their address, it's easier to ensure the relocations are aligned by padding with "nop" statements. In most dwarf sections this requirement is already fulfilled, only relocations for symbol address within the .debug_line section can be misaligned. * dwarf2dbg.c (out_set_addr): Align relocation within .debug_line.
2019-03-13dwarf2: Pad size of .debug_line section.Christian Eggers1-0/+11
As all dwarf debug information is organized in octets, the size of all dwarf sections must be aligned to OCTETS_PER_BYTE. Most DWARF sections meet this requirement, only the .debug_line section can reach an arbitrary octet size. In order to align the size to a multiple of OCTETS_PER_BYTE, the section is padded with "nop" statements at the end. * dwarf2dbg.c (out_debug_line): Pad size of .debug_line section.

2018-10-22PR23040, .uleb128 directive doesn't accept some valid expressionsAlan Modra1-8/+11
What a trip down a rabbit hole this bug has been. First observation: You can't use deferred_expression in s_leb128. deferred_expression implements the semantics of .eqv or '==', saving an expression with minimal simplification for assignment to a symbol so that the expression is evaluated at uses of the symbol. In particular, the value of "dot" is not evaluated at the .eqv symbol assignment, but later. When s_leb128 uses deferred_expression, "later" is at the end of assembly, giving entirely the wrong value of "dot". There is no way to fix this for the s_leb128 use without breaking .equ (which incidentally was already somewhat broken, see commit e4c2619ad1). So, don't use deferred_expression in s_leb128. But that leads to the gas test elf/dwarf2-17 failing, because view symbols are calculated with a chain of expression symbols. In the dwarf2-17 .L1 case there is a "temp_sym_1 > temp_sym_2" expression, with temp_sym_1 and temp_sym_2 on either side of a ".balign". Since ".balign" and many other directives moving "dot" are not calculated on the first (and only) pass over source, .L1 cannot be calculated until final addresses are assigned to frags. However, ".uleb128 .L1" *is* calculated immediately, resulting in the wrong value. The reason why .L1 is calculated immediately is that code in expr.c:operand after the comment /* If we have an absolute symbol or a reg, then we know its value now. */ does as it says and fixes the value of .L1, because .L1 is assigned to absolute_section in dwarf2dbg.c:set_or_check_view. So, correct that to expr_section. Unfortunately that fix leads to failure of the elf/dwarf2-5 test with ../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L5' ../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L11' ../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L12' So why is that? Well, it turns out that .L5 is defined in terms of .L4, and apparently .L4 is undefined. But .L4 clearly is defined, otherwise we would hit an error when trying to use .L4 a little earlier. There are two copies of .L4! So, symbols are cloned when that should not happen. Symbol cloning is a technique used by gas to support saving the value of symbols that change between uses, but that isn't the case with .L4. Only one value is set and used for .L4, but indeed .L4 was being cloned by symbol_clone_if_forward_ref. This despite no forward refs being present. Also, .L4 is a local symbol and a cursory glance at symbol_clone_if_forward_ref "if (symbolP && !LOCAL_SYMBOL_CHECK (symbolP))" would seem to prevent cloning of local symbols. All is not as it seems though, a curse of using macros. LOCAL_SYMBOL_CHECK modifies its argument if a "struct local_symbol" is converted to the larger "struct symbol", as happens when assigning a view symbol value. That fact results in the recursive call to symbol_clone_if_forward_ref returning a different address for "add_symbol". This problem could have been fixed by using symbol_same_p rather than comparing symbol pointers, but I thought it better to use the real symbol throughout. Note that symbol_find_exact also returns the real symbol for a converted local symbol. Finally, this patch does expose lack of support for forward symbol definitions in various targets. For example: alpha-linux +ERROR: ../ld/testsuite/ld-elf/pr11138-2.c: compilation failed This is caused by view symbol uses.

2015-06-15gas: Don't use frag_align but use plain padding to align .debug_aranges.Mark Wielaard1-2/+10
out_debug_aranges uses frag_align to make sure the addresses start out aligned. Using frag_align will call frag_var[_init], which will end up calling TC_FRAG_INIT. On arm and aarch64 TC_FRAG_INIT will generate a $d mapping symbol for the .debug_aranges to show that at that point a sequence of data items starts. Such a symbol pointing into a non-allocated debug section will confuse eu-strip -g. And it seems inefficient and wrong in general to have additional mapping symbols for debug sections, which won't contain actual code in the first place. Just keep track of the aranges header size and use plain padding to align the addresses which avoids generating any mapping symbols on aarch64 and arm. Includes a testcase for aarch64 that PASS with this patch and shows the extra $d mapping symbol in .debug_aranges before. gas/ChangeLog * dwarf2dbg.c (out_header): Document EXPR->X_add_number value, out_debug_aranges depends on it.

A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION to TC_CONS_FIX_NEW via static variables.
