John David Anglin 34360f080c parisc: improve ptrace support for gdb single-step ... Various GCC tests use gdb to simulate a multithreaded application. Many of these tests have been failing on parisc linux. GCC does this by using gdb to single-step the application, then gdb is used to call other test specific code. Where this fails is when the application is stepped into the delay slot of a taken branch. This sets the PSW B bit. When the test specific code is executed, this usually clears the PSW B bit. Currently, gdb is not allowed to set the B bit. So, the code falls through what should be a taken branch. The attached patch adds the PSW B bit to the set of bits that gdb is allowed to set. In order to set the B bit, the trace system call must return using an interrupt restore. The patch also modifies this code to use the saved IAOQ values when they are saved by a ptrace syscall or interruption.
