add infcall_mmap and gcc_target_options gdbarch methods
The compiler needed two new gdbarch methods. The infcall_mmap method allocates memory in the inferior. This is used when inserting the object code. The gcc_target_options method computes some arch-specific gcc options to pass to the compiler. This is used to ensure that gcc generates object code for the correct architecture. gdb/ChangeLog 2014-12-12 Jan Kratochvil <jan.kratochvil@redhat.com> * arch-utils.c (default_infcall_mmap) (default_gcc_target_options): New functions. * arch-utils.h (GDB_MMAP_PROT_READ, GDB_MMAP_PROT_WRITE) (GDB_MMAP_PROT_EXEC): Define. (default_infcall_mmap, default_gcc_target_options): Declare. * gdbarch.h: Rebuild. * gdbarch.c: Rebuild. * gdbarch.sh (infcall_mmap, gcc_target_options): New methods.
