Dear maintainer, golang-1.26 fails to build on riscv64 with an error in the testsuite: | ? cmd/compile/internal/staticinit [no test files] | ok cmd/compile/internal/syntax 0.398s | --- FAIL: TestMergeLocalsIntegration (0.52s) | mergelocals_test.go:181: =-= raw cand list for func ABC: | 0: integration.go:65:6 "p1" sz=8200 hp=true align=8 t=Pointery | 1: integration.go:65:10 "p2" sz=8200 hp=true align=8 t=Pointery | 2: integration.go:71:7 "xp3" sz=8200 hp=true align=8 t=Pointery2 | 3: integration.go:82:7 "xp4" sz=8200 hp=true align=8 t=Pointery2 | 4: integration.go:48:7 "v2" sz=8200 hp=false align=8 t=Vanilla | 5: integration.go:53:7 "v3" sz=8200 hp=false align=8 t=Vanilla2 | 6: integration.go:60:6 "s" sz=8192 hp=false align=8 t=Single | =-= addregion st=0 en=6: add part 0 -> 6 | | mergelocals_test.go:182: expected trace output on 8 vars got 0 | CODE: The full build log is available there: https://buildd.debian.org/status/fetch.php?pkg=golang-1.26&arch=riscv64&ver=1.26.6-2&stamp=1787146614&raw=0 The issue is perfectly reproductible, and does not happened with golang-1.27. Therefore I looked for and upstream fix, and I have found that commit which needs to be backported: https://github.com/golang/go/commit/5d5c7ff1f012bb70d653c1a2b282ee46161b6914 A proposed backport for the 1.26 branch is available here: https://go-review.googlesource.com/c/go/+/812900/2 With it the testsuite passes on riscv64.
