 Limitations of the morello port:
 
 - Building requires --disable-werror.
-- Profiling and --enable-profile are not supported (gperf, sprof, LD_PROFILE).
-- LD_AUDIT is not supported (symbind, PLT hooks, would require API redesign).
+- Profiling and --enable-profile are not supported (gprof, sprof, LD_PROFILE).
+- LD_AUDIT is not supported (la_symbind, PLT hooks, require new API redesign).
 - VDSO is not supported (depends on Linux work).
 - static-pie is not supported (requires start code redesign).
 - POSIX message queue async notify does not work (pointers passed via an fd).
-- Process shared robust mutexes don't work (pointers in shared memory).
+- Process shared robust mutex does not work (pointers in shared memory).
 - Purecap pldd only supports purecap ABI processes (not lp64).
 - malloc bounds narrowing has large overhead (locks and hash table lookup).
 - malloc bounds narrowing can break code expecting page granularity protection.
 	Use GLIBC_TUNABLES=glibc.mem.cap_narrowing=0 env var as a workaround.
 - string functions are not optimized.
-- Executable stacks are not supported.
+- Executable stack is not supported.
 - Internal pointer protection and pointer mangling are disabled.
