2
3 * include/mips-stub.h: Make C++ safe
4
5 * include/hal_cache.h (_hal_asm_mips_cpp_stringize): Add as a separate
6 macro because the compiler has got more picky
7
8 2000-03-16 Jonathan Larmour <jlarmour@redhat.co.uk>
9
10 * src/vectors.S (_start): Set return address to 0 and unconditionally
11 jump to cyg_start, so that GDB doesn't get confused with backtraces
12
13 2000-03-13 Nick Garnett <nickg@cygnus.co.uk>
14
15 * src/context.S :
16 Added jmpbuf_regsize to insulate jumb buffer from changes in
17 mips_regsize. This will need extra work if we go to a full 64 bit
18 variant, but for now is the simplest solution to this problem.
19
20 2000-02-25 Jonathan Larmour <jlarmour@redhat.co.uk>
21
22 * include/arch.inc: Add lpc and spc macros to save and restore PC
23 * src/context.S (hal_thread_switch_context): Restore RA into PC
24 location in context so that thread debugging works
25
