The newish test 'basic gdbstub support' fails for me on an out-of-the-box build on a host x86_64. (See below for the config.log head.)
Is this failure expected? If so, where can I see that in the various CI engines you have running them? In digging through the test driver python code in tests/tcg/multiarch/gdbstub/sha1.py I see that the test assumes that a breakpoint on the function SHA1Init is a breakpoint at the 1st assignment statement; the 1st next executes the 1st assignment statement, etc. This is a very fragile assumption. It depends on the compiler used to compile sha1.c; it depends on the optimization level; it depends on the accuracy of the pc mapping in the debug info; it depends on gdb. Better would be to change SHA1Init to do its work, and then call another non-inlined function taking a context pointer, and then examine context->state[0] and context->state[1].
