2021-02-17read_leb128 overflow checkingAlan Modra10-56/+183
There is a tiny error left in dwarf.c:read_leb128 after Nick fixed the signed overflow problem in code I wrote. It's to do with sleb128 values that have unnecessary excess bytes. For example, -1 is represented as 0x7f, the most efficient encoding, but also as 0xff,0x7f or 0xff,0xff,0x7f and so on. None of these sequences overflow any size signed value, but read_leb128 will report an overflow given enough excess bytes. This patch fixes that problem, and since the proper test for signed values with excess bytes can easily be adapted to also test a sleb byte with just some bits that overflow the result, I changed the code to not use signed right shifts. (The C standard ISO/IEC 9899:1999 6.5.7 says signed right shifts of negative values have an implementation defined value. A long time ago I even used a C compiler for a certain microprocessor that always did unsigned right shifts. Mind you, it is very unlikely to be compiling binutils with such a compiler.) bfd/ * wasm-module.c: Guard include of limits.h. (CHAR_BIT): Provide backup define.

2021-02-17RISC-V: PR27200, allow the first input non-ABI binary to be linked with any one.Nelson Chu2-14/+25
RISC-V only defines two float ABIs, soft-float and double-float, and the value of soft-float is 0x0. But 0x0 usually means unknown/default setting for many targets, and the non-ABI binary, which is generated by "ld/objcopy -b binary", also has the 0x0 elf header flags, this may be confused. We probably can define a new unknown/default ABI value to make them more clear, but that will need more bits in the elf header flags, and also need to discuss in the riscv psabi spec. Training linker have a default ABI setting, and can be changed by ld options or configure options is another solution, like what assemblr usually do. So all objects, including the binary files, will have explicit ABI setting. But the binary files will no longer be linked with any object, users need to recompile them with the exactly ABI they want. It may be inconvenience sometimes. Besides, I think linker doesn't need to know the default arch/abi so far, just set them according to the linked objects should be enough. Therefore, without changing the riscv psabi, and keep the non-ABI binary can be linked with any object, we don't check the ABI flags if no code section in the PR24389. Just that we find the first input non-ABI binary still cannot be linked with others in the PR27200. This patch fixs the problem by delaying the elf_flags_init(obfd) check, since the flags of non-ABI object with no code cannot be copyed to output BFD, we should skip it, even if it is the first linked object. However, there is a strange "break" at the end of loop in the PR24389. The "break" cause the ld testcase "Link with zlib-gabi compressed debug output 1" fails for rv64gc-linux toolchain, after applying the above change. The root cause is that - the "break" make linker only checks the "first" section of input BFD rather than the entire sections. I have checked that AARCH64 and ARM both have the "break" at the end of loop, but ARC doesn't. I suppose we should remove the "break" like what ARC do, or use a pair of braces for the if statement. I have passed the elf/linux toolchain regressions, so the change should be fine. bfd/ PR 27200 * elfnn-riscv.c (_bfd_riscv_elf_merge_private_bfd_data): Delay copying the elf flags from input BFD to output BFD, until we have checked if the input BFD has no code section or not. Also fix the problem that we only check the first section rather than the entire sections for input BFD.

2021-02-16x86: CVTPI2PD has special behaviorJan Beulich18-95/+203
CVTPI2PD with a memory operand, unlike CVTPI2PS, doesn't engage MMX logic. Therefore it - has a proper AVX equivalent (CVTDQ2PD) and hence can be subject to SSE2AVX translation and SSE checking, - should not record MMX use in the respective ELF note.

This undoes a change to md_assemble() that 32930e4edbc0 ("x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker") did without any explanation. This broke a CVTPI2PS property test that a subsequent test will add, and the updates to existing tests also demonstrate what was wrong: For example, AVX insns update the full YMM, even if a Vex128 variant is in use.

In particular many tests are skipped without reporting an error if no target C compiler is found, but if a target C compiler is found but won't compile a testcase for some reason we used to mark the test as unresolved.

2021-02-11[gdb/symtab] Handle DW_FORM_strx in form_requires_reprocessingTom de Vries2-1/+8
When running test-case gdb.dwarf2/fission-mix.exp using gcc-11, I run into: ... (gdb) file fission-mix^M Reading symbols from fission-mix...^M src/gdb/dwarf2/attribute.h:258: internal-error: \ void attribute::set_unsigned_reprocess(ULONGEST): \ Assertion `form_requires_reprocessing ()' failed.^M ... This happens when calling set_unsigned_reprocess on an attribute with form DW_FORM_strx. The assert triggers because DW_FORM_strx is not listed in form_requires_reprocessing. Fix this by adding DW_FORM_strx in form_requires_reprocessing. Tested on x86_64-linux. gdb/ChangeLog: 2021-02-11 Tom de Vries <tdevries@suse.de> PR symtab/27353 * dwarf2/attribute.c (attribute::form_requires_reprocessing): Return true for DW_FORM_strx.
