Hey Kevin,
I've just noticed that this patch series has introduced new FAILs when
testing a 64-bit GDB with --target_board unix/-m32:
new FAIL: gdb.python/py-thrhandle.exp: thread 0: fetch thread handle from thread
new FAIL: gdb.python/py-thrhandle.exp: thread 0: verify that handles are the same
new FAIL: gdb.python/py-thrhandle.exp: thread 1: fetch thread handle from thread
new FAIL: gdb.python/py-thrhandle.exp: thread 1: verify that handles are the same
new FAIL: gdb.python/py-thrhandle.exp: thread 2: fetch thread handle from thread
new FAIL: gdb.python/py-thrhandle.exp: thread 2: verify that handles are the same
The build logs:
https://gdb-build.sergiodj.net/builders/Fedora-x86_64-m32/builds/12263
And the testsuite logs:
https://gdb-build.sergiodj.net/results/Fedora-x86_64-m32/94/947210e5690c61b395ccd887bc58bcb45ccd357b/
I haven't been able to investigate further, sorry.
Thanks,
