The command @samp{thread @var{n}} will select thread @var{n}, -@c OBSOLETE shifting the debugger's attention to it for single-stepping, -@c OBSOLETE registers, local memory, and so on. -@c OBSOLETE -@c OBSOLETE @kindex info threads -@c OBSOLETE The @samp{info threads} command will show what threads, if any, have -@c OBSOLETE invisibly hit breakpoints or signals and are waiting to be noticed. -@c OBSOLETE -@c OBSOLETE @kindex set parallel -@c OBSOLETE The @samp{set parallel} command controls how many threads can be active. -@c OBSOLETE -@c OBSOLETE @table @code -@c OBSOLETE @item set parallel off -@c OBSOLETE One thread. Requests by the program that other threads join in -@c OBSOLETE (spawn and pfork instructions) do not cause other threads to start up. -@c OBSOLETE This does the same thing as the @samp{limit concurrency 1} command. -@c OBSOLETE -@c OBSOLETE @item set parallel fixed -@c OBSOLETE All CPUs are assigned to your program whenever it runs. When it -@c OBSOLETE executes a pfork or spawn instruction, it begins parallel execution -@c OBSOLETE immediately. This does the same thing as the @samp{mpa -f} command. -@c OBSOLETE -@c OBSOLETE @item set parallel on -@c OBSOLETE One or more threads. Spawn and pfork cause CPUs to join in when and if -@c OBSOLETE they are free. This is the default. It is very good for system -@c OBSOLETE throughput, but not very good for finding bugs in parallel code. If you -@c OBSOLETE suspect a bug in parallel code, you probably want @samp{set parallel fixed.} -@c OBSOLETE @end table -@c OBSOLETE -@c OBSOLETE @subsection Limitations -@c OBSOLETE -@c OBSOLETE WARNING: Convex GDB evaluates expressions in long long, because S -@c OBSOLETE registers are 64 bits long. However, GDB expression semantics are not -@c OBSOLETE exactly C semantics. This is a bug, strictly speaking, but it's not one I -@c OBSOLETE know how to fix. If @samp{x} is a program variable of type int, then it -@c OBSOLETE is also type int to GDB, but @samp{x + 1} is long long, as is @samp{x + y} -@c OBSOLETE or any other expression requiring computation. So is the expression -@c OBSOLETE @samp{1}, or any other constant. You only really have to watch out for -@c OBSOLETE calls. The innocuous expression @samp{list_node (0x80001234)} has an -@c OBSOLETE argument of type long long. You must explicitly cast it to int. -@c OBSOLETE -@c OBSOLETE It is not possible to continue after an uncaught fatal signal by using -@c OBSOLETE @samp{signal 0}, @samp{return}, @samp{jump}, or anything else. The difficulty is with -@c OBSOLETE Unix, not GDB. -@c OBSOLETE -@c OBSOLETE I have made no big effort to make such things as single-stepping a -@c OBSOLETE @kbd{join} instruction do something reasonable. If the program seems to -@c OBSOLETE hang when doing this, type @kbd{ctrl-c} and @samp{cont}, or use -@c OBSOLETE @samp{thread} to shift to a live thread. Single-stepping a @kbd{spawn} -@c OBSOLETE instruction apparently causes new threads to be born with their T bit set; -@c OBSOLETE this is not handled gracefully. When a thread has hit a breakpoint, other -@c OBSOLETE threads may have invisibly hit the breakpoint in the background; if you -@c OBSOLETE clear the breakpoint gdb will be surprised when threads seem to continue -@c OBSOLETE to stop at it. All of these situations produce spurious signal 5 traps; -@c OBSOLETE if this happens, just type @samp{cont}. If it becomes a nuisance, use -@c OBSOLETE @samp{handle 5 nostop}. (It will ask if you are sure. You are.) -@c OBSOLETE -@c OBSOLETE There is no way in GDB to store a float in a register, as with -@c OBSOLETE @kbd{set $s0 = 3.1416}. The identifier @kbd{$s0} denotes an integer, -@c OBSOLETE and like any C expression which assigns to an integer variable, the -@c OBSOLETE right-hand side is casted to type int. If you should need to do -@c OBSOLETE something like this, you can assign the value to @kbd{@{float@} ($sp-4)} -@c OBSOLETE and then do @kbd{set $s0 = $sp[-4]}. Same deal with @kbd{set $v0[69] = 6.9}. - diff --git a/gdb/config/convex/convex.mh b/gdb/config/convex/convex.mh deleted file mode 100644 index 5ec3bfe..0000000 --- a/gdb/config/convex/convex.mh +++ /dev/null @@ -1,3 +0,0 @@ -# OBSOLETE # Host: Convex Unix (4bsd) -# OBSOLETE XDEPFILES= convex-xdep.o -# OBSOLETE XM_FILE= xm-convex.h diff --git a/gdb/config/convex/convex.mt b/gdb/config/convex/convex.mt deleted file mode 100644 index 425b171..0000000 --- a/gdb/config/convex/convex.mt +++ /dev/null @@ -1,3 +0,0 @@ -# OBSOLETE # Target: Convex Unix (4bsd) -# OBSOLETE TDEPFILES= convex-tdep.o -# OBSOLETE TM_FILE= tm-convex.h diff --git a/gdb/config/convex/tm-convex.h b/gdb/config/convex/tm-convex.h deleted file mode 100644 index 5ddd1f4..0000000 --- a/gdb/config/convex/tm-convex.h +++ /dev/null @@ -1,486 +0,0 @@ -/* OBSOLETE /* Definitions to make GDB run on Convex Unix (4bsd) */ -/* OBSOLETE Copyright 1989, 1991, 1993 Free Software Foundation, Inc. */ -/* OBSOLETE */ -/* OBSOLETE This file is part of GDB. */ -/* OBSOLETE */ -/* OBSOLETE This program is free software; you can redistribute it and/or modify */ -/* OBSOLETE it under the terms of the GNU General Public License as published by */ -/* OBSOLETE the Free Software Foundation; either version 2 of the License, or */ -/* OBSOLETE (at your option) any later version. */ -/* OBSOLETE */ -/* OBSOLETE This program is distributed in the hope that it will be useful, */ -/* OBSOLETE but WITHOUT ANY WARRANTY; without even the implied warranty of */ -/* OBSOLETE MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
