1635139 - Local Talos profiling symbolication on Windows requires "mach buildsymbols"

Status: NEW

(Testing :: Talos, defect, P3)

Description

[Markus Stange [:mstange]]

When you run mach talos-test --geckoProfile [...] locally, on Windows, the resulting profiler recordings do not have symbols for xul.dll, unless you run mach buildsymbols first.

On macOS and Linux, they have symbols even without mach buildsymbols, because symbolication.py will use dump_syms_mac or nm to get symbols.

We could land a Windows version of dump_syms in there as well, and use that. There are probably other cleaner solutions.
(For example, these days we have taskcluster jobs which produce dump_syms artifacts, so there's probably a way to download the artifact from the latest such job, rather than putting a binary into the source tree.)

Bug 1720356 would fix this.
