The main aim of this patchset is patch 2, which changes the coroutine backend selection logic so that it goes 'ucontext -> sigaltstack' rather than 'ucontext -> gthread', since the gthread backend is broken. To do this properly on all platforms we have to refactor the code a bit (which it needed anyway).
The first patch here is a generic configure cleanup to how we print error messages, which I wanted for the third patch because otherwise the various error paths would have been rather verbose. Changes v1->v2: * fix the tests makefile too * CONFIG_COROUTINE_BACKEND=foo rather than CONFIG_FOO_COROUTINE=y; this simplifies both the configure code and the makefiles * dropped the 'move upper()' patch as no longer needed (in this series, anyway) Peter Maydell (2): configure: Provide and use convenience error reporting function configure: Don't fall back to gthread coroutine backend Makefile.objs | 11 +-- configure | 257 ++++++++++++++++++++++++++------------------------------ tests/Makefile | 14 +-- 3 files changed, 119 insertions(+), 163 deletions(-) -- 1.7.9.5
