2013-04-22Andrew Haley found a bug on GDB running on ARM when usingSergio Durigan Junior5-1/+77
--enable-64-bit-bfd. Basically the issue happens when dealing with "bl" instructions: GDB does branch destination calculation and (wrongly) sign-extends the PC. Here is a piece of his original message explaining the problem: > next_pc = arm_get_next_pc (frame, get_frame_pc (frame)); > > /* The Linux kernel offers some user-mode helpers in a high page. We can > not read this page (as of 2.6.23), and even if we could then we couldn't > set breakpoints in it, and even if we could then the atomic operations > would fail when interrupted. They are all called as functions and return > to the address in LR, so step to there instead. */ > if (next_pc > 0xffff0000) > next_pc = get_frame_register_unsigned (frame, ARM_LR_REGNUM); > > arm_insert_single_step_breakpoint (gdbarch, aspace, next_pc); > > Unfortunately, branch destination addresses are SIGN EXTENDED to 64 > bits. So, > > (top-gdb) p/x next_pc > $14 = 0xffffffffb6df2864 > > Which triggers the next_pc = get_frame_register_unsigned(), and we > cannot step into any branches because the destination PC is wrong. Anyway, the fix is simple and Andrew himself provided it for us. It took a while for me to figure out how to trigger the bug (in order to write a testcase for it), but I finally made it. The attached patch fixes the problem (by casting to `unsigned long' instead of just `long'), and also includes a testcase to reproduce the issue. gdb/ChangeLog: 2013-04-22 Andrew Haley <aph@redhat.com> * arm-tdep.c (BranchDest): Cast result as "unsigned long", instead of "long". gdb/testsuite/ChangeLog: 2013-04-22 Sergio Durigan Junior <sergiodj@redhat.com> * gdb.arch/arm-bl-branch-dest.c: New file. * gdb.arch/arm-bl-branch-dest.exp: Likewise.

2013-04-19-Wpointer-sign: ctf.c.Pedro Alves2-7/+13
ctf_save_write's second parameter is gdb_byte *, and all these arguments are 'char *'. Since this function is ultimately just writing host bytes to a local file with fwrite, an alternative would be to change ctf_save_write to take a 'void *' instead of 'gdb_byte *', thus removing the need for any cast (we have more calls with casts than without). gdb/ 2013-04-19 Pedro Alves <palves@redhat.com> * ctf.c (ctf_write_uploaded_tsv, ctf_write_uploaded_tp): Add casts to 'gdb_byte *'.
