Zero pull requests were merged this week, with 30 additional commits pushed directly to the main branch.
Starting with tooling improvements, Alan Donovan modernized the vet and fix tools by migrating them to use new analyzer suite constants from the x/tools package. This change removes substantial duplicate code and makes it easier for third parties to create custom analysis tools that track the official suites. The…
Cherry Mui delivered a significant enhancement by updating the vendored x/arch library to add AVX instruction support in the disassembler. This addresses issue 78065 and brings modern x86 instruction set support to Go's debugging tools.
On the bug fix front, Russ Cox resolved a critical issue in the internal strconv package where long numeric outputs contained null bytes instead of zeros due to incorrect middle digit count calculations. The fix came with community contribution from rokkerruslan, who provided both analysis and test cases.
Cherry Mui also fixed a compiler bug affecting static initialization of structs with embedded fields. The compiler wasn't properly calculating field offsets…
