7 * cdl/redboot.cdl: Added option
8 CYGOPT_REDBOOT_BSP_SYSCALLS_EXIT_WITHOUT_TRAP for enabling (possibly
9 single shot) programs to exit and return a termination status as
10 their normal behavior (i.e. without raising a SIGTRAP).
11 * src/syscall.c (__do_syscall): Added conditionally compiled code
12 to SYS_exit for returning to RedBoot main loop without raising a
13 SIGTRAP, even when the calling program is not being debugged.
14 * src/main.c (cyg_start): Added code (following Jonathan Larmour's
15 and Mark Salter's suggestions) to RedBoot main loop: a (context)
16 savepoint is created before the thread of control is transferred to
17 gdb stubs (through a trampoline procedure). This savepoint enables
18 the stubs to return control back to the main loop by calling the
19 return_to_redboot procedure (macro CYGACC_CALL_IF_MONITOR_RETURN).
20 Procedure go_trampoline and variables go_saved_context and
21 go_return_status have been respectively renamed to trampoline,
22 saved_context and return_status.
