2022-03-23gas/Dwarf5: adjust .debug_line file 0 checkingJan Beulich1-11/+10
First of all when a table entry has a NULL filename, the two inner if()s are better done the other way around: The 2nd doesn't depend on what the first does. This then renders redundant half of the conditions of the other if() and clarifies that subsequently only entry 0 is dealt with (indicating that part of the comment was wrong). Finally for there to be a usable name in slot 1, files_in_use needs to be larger than 1 and slot 1's (rather than slot 0's) name needs to be non-NULL.
2022-03-23gas/Dwarf5: drop dead codeJan Beulich1-11/+3
Commit 3417bfca676f ("GAS: DWARF-5: Ensure that the 0'th entry in the directory table contains the current... ") added a "dwarf_level < 5" check to out_dir_and_file_list(). This rendered dead that branch of the construct, due to the enclosing if()'s "DWARF2_LINE_VERSION >= 5". Delete that code as well as the corresponding part of the comment. While there also drop a redundant "dirs != NULL": "dirs" will always be non-NULL when dirs_in_use is not zero.
2022-03-23gas/Dwarf: improve debug info generation from .irp and alike blocksJan Beulich4-5/+116
Tying the bumping of the logical line number to reading from the original source file looks wrong: Upon finishing of the processing of an sb the original values will be restored anyway. Yet without bumping the line counter uses of .line inside e.g. an .irp construct won't have the intended effect: Such uses may be necessary to ensure proper debug info is emitted in particular when switching sections inside the .irp body, as dwarf2_gen_line_info() would bail without doing anything when it finds the line number unchanged from what it saw last.
2022-03-23ELF32: don't silently truncate relocation addendsJan Beulich6-9/+23
At least x86-64's x32 sub-mode and RISC-V's 32-bit mode calculate addends as 64-bit values, but store them in signed 32-bit fields when generating the file without encountering any earlier error. When the relocated field is a 64-bit one, the value resulting after processing the relocation record when linking (or the latest when loading) may thus be wrong due to the truncation. With the code change in place, one x32 testcase actually triggers the new diagnostic. That one case of too large a (negative) addend is being adjusted alongside the addition of a new testcase to actually trigger the new error. (Note that due to internal BFD behavior the relocation in .data doesn't get processed anymore after the errors in .text.) Note that in principle it is possible to express 64-bit relocations in ELF32, but this would require .rel relocations, i.e. with the addend stored in the 64-bit field being relocated. But I guess it would be a lot of effort for little gain to actually support this.
2022-03-23gas: retain whitespace between stringsJan Beulich5-3/+67
Macro arguments may be separated by commas or just whitespace. Macro arguments may also be quoted (where one level of quotes is removed in the course of determining the values for the respective formal parameters). Furthermore this quote removal knows _two_ somewhat odd escaping mechanisms: One, apparently in existence forever, is that a pair of quotes counts as the escaping of a quote, with the pair being transformed to a single quote in the course of quote removal. The other (introduced by c06ae4f232e6) looks more usual on the surface in that it deals with \" sequences, but it _retains_ the escaping \. Hence only the former mechanism is suitable when the value to be used by the macro body is to contain a quote. Yet this results in ambiguity of what "a""b" is intended to mean; elsewhere (e.g. for .ascii) it represents two successive string literals. However, in any event is the above different from "a" "b": I don't think this can be viewed the same as "a""b" when processing macro arguments. Change the scrubber to retain such whitespace, by making the processing of strings more similar to that of symbols. And indeed this appears to make sense when taking into account that for quite a while gas has been supporting quoted symbol names. Taking a more general view, however, the change doesn't go quite far enough. There are further cases where significant whitespace is removed by the scrubber. The new testcase enumerates a few in its ".if 0" section. I'm afraid the only way that I see to deal with this would be to significantly simplify the scrubber, such that it wouldn't do much more than collapse sequences of unquoted whitespace into a single blank. To be honest problems in this area aren't really surprising when seeing that there's hardly any checking of .macro use throughout the testsuite (and in particular in the [relatively] generic tests under all/).
2022-03-21x86: don't suppress overflow diagnostics in x32 modeJan Beulich3-1/+30
Unlike in 64-bit mode, where values wrap at the 64-bit boundary anyway, there's no wrapping at the 32-bit boundary here, and hence overflow detection shouldn't be suppressed just because rela relocations are going to be used. The extra check against NO_RELOC is actually a result of an ilp32 test otherwise failing. But thinking about it, reporting overflows for not-really-relocations (typically because of earlier errors) makes little sense in general. Perhaps this should even be extended to non- 64-bit modes.

2022-03-20PR28979, internal error in demand_empty_rest_of_lineAlan Modra1-6/+14
The change in read_a_source_file prevents the particular testcase in the PR from triggering the assertion in demand_empty_rest_of_line. I've also removed the assertion. Nothing much goes wrong with gas if something else triggers it, so it's not worthy of an abort. I've also changed my previous patch to ignore_rest_of_line to allow that function to increment input_line_pointer past buffer_limit, like demand_empty_rest_of_line: The two functions ought to behave the same in that respect. Finally, demand_empty_rest_of_line gets a little hardening to prevent accesses past buffer_limit plus one.

2022-03-18x86: also fold remaining multi-vector-size shift insnsJan Beulich1-7/+9
By slightly relaxing the checking in operand_type_register_match() we can fold the vector shift insns with an XMM source as well. While strictly speaking an overlap in just one size (see the code comment) is not enough (both operands could have multiple sizes with just a single common one), this is good enough for all templates we have, or which could sensibly / usefully appear (within the scope of the present operand matching model). Tightening this a little would be possible, but would require broadcast related information to be passed into the function.

2022-03-17x86: don't accept base architectures as extensionsJan Beulich4-1/+5
The -march= intentions are quite clear: A base architecture may be followed by any number of extensions. Accepting a base architecture in place of an extension will at best result in confusion, as the first of the two (or more) items specified simply would not take effect, due to being overridden by the later one(s).
2022-03-17x86: add another IAMCU testcaseJan Beulich2-2/+7
Now that {L,K}1OM support is gone, and with it the brokenness in check_cpu_arch_compatible(), put in place a test making sure that only extensions can be enabled via .arch for IAMCU, and that the base architecture cannot be changed.
2022-03-17x86: drop L1OM/K1OM support from gasJan Beulich11-607/+10
This was only rudimentary support anyway; none of the sub-architecture specific insns were ever supported.
2022-03-17x86: assorted IAMCU CPU checking fixesJan Beulich4-4/+10
The checks done by check_cpu_arch_compatible() were halfway sensible only at the time where only L1OM support was there. The purpose, however, has always been to prevent bad uses of .arch (turning off the base CPU "feature" flag) while at the same time permitting extensions to be enabled / disabled. In order to achieve this (and to prevent regressions when L1OM and K1OM support are removed) - set CpuIAMCU in CPU_IAMCU_FLAGS, - adjust the IAMCU check in the function itself (the other two similarly broken checks aren't adjusted as they're slated to be removed anyway), - avoid calling the function for extentions (which would never have the base "feature" flag set), - add a new testcase actually exercising ".arch iamcu" (which would also regress with the planned removal).

2022-03-16PowerPC64 extended instructions in powerpc_macrosAlan Modra3-16/+16
The extended instructions implemented in powerpc_macros aren't used by the disassembler. That means instructions like "sldi r3,r3,2" appear in disassembly as "rldicr r3,r3,2,61", which is annoying since many other extended instructions are shown. Note that some of the instructions moved out of the macro table to the opcode table won't appear in disassembly, because they are aliases rather than a subset of the underlying raw instruction. If enabled, rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all occurrences of rotldi, rldicl, rldicr, rldic and rldimi. (Or many occurrences in the case of clrlsldi if n <= b was added to the extract functions.)

2022-02-16gas local label and dollar label handlingAlan Modra5-131/+71
Much of the gas source and older BFD source use "long" for function parameters and variables, when other types would be more appropriate. This patch fixes one of those cases. Dollar labels and numeric local labels do not need large numbers. Small positive itegers are usually all that is required. Due to allowing longs, it was possible for fb_label_name and dollar_label_name to overflow their buffers. * symbols.c: Delete unnecessary forward declarations. (dollar_labels, dollar_label_instances): Use unsigned int. (dollar_label_defined, dollar_label_instance): Likewise. (define_dollar_label): Likewise. (fb_low_counter, fb_labels, fb_label_instances): Likewise. (fb_label_instance_inc, fb_label_instance): Likewise. (fb_label_count, fb_label_max): Make them size_t. (dollar_label_name, fb_label_name): Rewrite using sprintf. * symbols.h (dollar_label_defined): Update prototype. (define_dollar_label, dollar_label_name): Likewise. (fb_label_instance_inc, fb_label_name): Likewise. * config/bfin-lex.l (yylex): Remove unnecessary casts. * expr.c (integer_constant): Likewise. * read.c (read_a_source_file): Limit numeric label range to int.
2022-02-16ubsan: s_app_line integer overflowAlan Modra1-9/+8
There are quite a few ubsan warnings in gas. This one disappears with a code tidy. * read.c (s_app_line): Rename 'l' to 'linenum'. Avoid ubsan warning.
2022-02-16asan : use of uninitialized value in buffer_and_nestAlan Modra1-9/+20
* macro.c (buffer_and_nest): Don't read past end of string buffer.

This was needed when gas was using the automake cygnus option, but this was removed years ago by Simon in d0ac1c44885daf68f631befa37e ("Bump to autoconf 2.69 and automake 1.15.1"). So delete it here. The info pages are already & still installed by default w/out it.
