4Subject: [PATCH] Fix build with latest GCC 9.0 tree
5
6A recent patch [1] to fix a GCC PR [2] actually broke the GDB build.
7To fix, remove the stack pointer clobber. GCC will ignore the clobber
8marker, and will not save or restore the stack pointer.
9
10I ran "make check-gdb" on x86_64 to ensure there are no regressions.
