An all-in-one patch that fixes several issues:
|
|
|
|
1) UnscaledCycleClock not fully implemented for ppc*-musl (disabled on musl)
|
|
2) powerpc stacktrace implementation only works on glibc (disabled on musl)
|
|
3) powerpc stacktrace implementation has ppc64 assumptions (fixed)
|
|
4) examine_stack.cpp makes glibc assumptions on powerpc (fixed)
