[Bug binutils/27686] New: windres: fails with "nul bytes found in version string"
https://sourceware.org/bugzilla/show_bug.cgi?id=27686 Bug ID: 27686 Summary: windres: fails with "nul bytes found in version string" Product: binutils Version: unspecified Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: mark at harmstone dot com Target Milestone: --- Created attachment 13343 --> https://sourceware.org/bugzilla/attachment.cgi?id=13343&action=edit patch Recent versions of RC.EXE seem to add more padding to the end of version blocks than windres is expecting, leading to this error message. I probably can't attach a sample here, but this is the case for all versions of Windows 10 Notepad that I've encountered - let me know if you can't reproduce. The solution would seem to be for windres to only consider the stated length of the version block, and ignore the length of the surrounding resource entry - see the attached patch, which fixes the issue. -- You are receiving this mail because: You are on the CC list for the bug.
[Bug gas/27687] New: gas should allow question marks in labels for x86 asm
https://sourceware.org/bugzilla/show_bug.cgi?id=27687 Bug ID: 27687 Summary: gas should allow question marks in labels for x86 asm Product: binutils Version: unspecified Status: UNCONFIRMED Severity: normal Priority: P2 Component: gas Assignee: unassigned at sourceware dot org Reporter: mark at harmstone dot com Target Milestone: --- Created attachment 13344 --> https://sourceware.org/bugzilla/attachment.cgi?id=13344&action=edit patch There doesn't seem to be currently any way to get gas to accept question marks in labels for x86 assembly. This - "?label": jmp ?label - fails with "Error: invalid character '?' before operand 1". The use case for this is MSVC's C++ name mangling, which uses question marks extensively - there seems to be no way to call MSVC C++ functions from gas. Attached is a patch which defines LEX_QM in gas/config/tc-i386.h, which seems to fix the issue. -- You are receiving this mail because: You are on the CC list for the bug.
[Bug gas/27688] New: gas does not support .secidx pseudo-directive
https://sourceware.org/bugzilla/show_bug.cgi?id=27688 Bug ID: 27688 Summary: gas does not support .secidx pseudo-directive Product: binutils Version: unspecified Status: UNCONFIRMED Severity: normal Priority: P2 Component: gas Assignee: unassigned at sourceware dot org Reporter: mark at harmstone dot com Target Milestone: --- Created attachment 13345 --> https://sourceware.org/bugzilla/attachment.cgi?id=13345&action=edit secidx patch llvm-mc has a pseudo-directive .secidx for COFF files, which maps to a IMAGE_REL_I386_SECTION / IMAGE_REL_AMD64_SECTION relocation entry. This is a two-byte field which gets set to the section index of a label when it's linked. This is necessary for support for CodeView / PDB debugging, as addresses are represented by a two-byte section index and a four-byte offset (i.e. a .secidx and a .secrel32). See also my CodeView patches to the gcc mailing list, which rely on this to work. I've attached a patch, which implements this for x86 and amd64. -- You are receiving this mail because: You are on the CC list for the bug.
