Some examples of failing tests from the GCC testsuite are gcc.dg/pr78185.c and gcc.dg/cleanup-10.c. + +Some problems I've identified and tried to fix with the attached patch are: + +- Code copied from the Linux kernel wasn't adjusted to differentiate between host and target data types and address spaces. + +- The sigaltstack() system call returns EINVAL because fields are listed in the wrong order in struct target_sigaltstack. + +With this patch, the system calls to set up the signal handler are returning successfully, but the handler isn't being invoked, so something is still wrong. I think I need another pair of eyes to look over this code. \ No newline at end of file |
