Note: The following has only been tested with N32, but can probably
be made to work with a small number of adjustments.
On mips-irix, the sigcontext_t structure is stored at the base
of the frame established by the _sigtramp function. The definition
of this structure can be found in <sys/signal.h> (comments have been

used by this comment):

// General purpose registers

// Floating point coprocessor state
__uint64_t sc_fpregs[32]; // fp regs 0 to 31

support for mips-irix on-stack trampolines On mips-irix, the debugger has trouble stepping over the following line of code: S: Shape'Class := R; <<<<---- STOP here Here is what happens: (gdb) n warning: GDB can't find the start of the function at 0x7fff2bd8. GDB is unable to find the start of the function at 0x7fff2bd8 and thus can't determine the size of that function's stack frame. This means that GDB may be unable to access that stack frame, or the frames below it. This problem is most likely caused by an invalid program counter or stack pointer. However, if you think GDB should simply search farther back from 0x7fff2bd8 for code which looks like the beginning of a function, you can increase the range of the search using the `set heuristic-fence-post' command. 0x7fff2bd8 in ?? () The program does in fact jump to this code location, which is a trampoline located on the stack (there is an implicit call to a routine internally generated by the Ada expander).
