06f18c1c0d XXX: GCC uninitialized variable. 2006-05-14 02:15:31 +00:00

2b4ccae3e9 Remove pt_blockuc. If the debugger attempts to muck with the state of a 
blocked thread, return an error; this should be done through ptrace(2).

94a458cedd enhance MI pthreads code to support hppa: 
- statically initialize all global spin locks.  on hppa, 0 means
   the lock is held, so leaving them with the default value doesn't work.
 - compare functions pointers using a function-pointer type rather than
   an integral type.  on hppa, function pointers may be indirect,
   so we need to trigger gcc to emit calls to the function-pointer
   canonicalization routines in the millicode.
 - on hppa the stack grows up, so handle that using the STACK_* macros.

3a30736db7 td_sync_info(): explicitly clear the "locked" flag when unlocked,

Problem reported by Havard Eidnes while building evbsh5.

7347018381 Ouch. Lint didn't like the last change on sparc64. The reason: 
<machine/reg.h> plays dirty naming tricks on sparc64 to allow 32bit
compatibility (reg ->  reg64 and the parameter in
PTHREAD_REG_TO_UCONTEXT() is called reg). This probably needs to be
fixed separately, but for now reordering the includes will do.

41e871fe18 Avoid depending on declarations of struct reg and struct fpreg by using 
the proc_regsize() callback to allocate reg and fpreg buffers as part of the
proc state (lazily initialized by the PT_STATE_RUNNING case of
td_thr_suspend()).

Fixes build on sh3 (and probably sh5) platforms.

568717a98d Get the td_thread_t * corresponding to nthread to mess with its lwp 
data, rather than trying a nonsensical operation on a caddr_t from a
different address space.

Moral: test-compile in the same tree you're working in.

bff67c76fe Add an offset to the thread ID numbers, because GDB really doesn't

24ddb5f789 td_map_lwps(): there's always one lwp. This makes the call work before 
the thread system has started.

Additionally, mark not-on-LWP threads explicitly, so that there's no
risk of using stale information.

0a6afcc70d Rename pt_stacksize, pt_stacksize_lg, and pt_stackmask to pthread_*. External 
symbols can't start with pt_, as that is in the application namespace.

b2f27acb27 Do all the symbol lookups at td_open() time and cache them in the td_proc_st. 
Make the stacksize lookups and data part of td_proc_st rather than global state.

f85d2d1c14 Use ${HOST_SH} instead of `sh'. 
If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

6a0c6dddb7 Preferentially read context pointer from pt_trapuc. 2003-06-26 21:51:59 +00:00
nathanw
64b72cb09f A couple of READ calls in td_sync_info() were reading into a 
pthread_spin_t variable (4 bytes) but telling read that they were
reading sizeof(struct pthread_spinlock_st) (12 bytes). This led to
overwriting other things on the stack, like the return address. Oops.

Fix by changing READ call here (and elsewhere, for future safety) to:
  READ(,, &variable, sizeof(variable))
instead of
  READ(,, &variable, sizeof(type)).

Fixes a crash in gdb when running "thread examine all" reported by
Bill Studenmund.
