4b2d74f656 fix merge conflict bug preventing the bootimage code from seeing, marking, and fixing jsr addresses 2009-02-14 14:23:23 -07:00

f58f7b3bdf fix bugs pertaining to tracking reads and and value sites across subroutines (jsr and ret instructions) 2009-02-14 13:26:39 -07:00
Joel Dice
93142bb952 support filtering based on class name, method name, and method spec in
bootimage.cpp

This is useful for debugging the compiler, since it allows you to
compile one method in particular if that's where a bug manifests itself.

4717e94fa3 remove value buddies after setting sites to junction sites, not after populating junction sites
This mirrors how snapshots are captured and restored for branch events.
Also, switch back to resolving junction sites before capturing fork
snapshots so we capture the true state of each value immediately before
the branch.

6f1d02dae7 remove the libstdc++ dependency once and for all
The trick is to make all destructors non-virtual.  This is safe because
we never use the delete operator, which is the only case where virtual
destructors are relevant.  This is a better solution than implementing
our own delete operator, because we want libraries loaded at runtime to
use the libstdc++ version, not ours.

6a5116e7a7 implement primitive heap dump facility for memory profiling, accessible via Runtime.dumpHeap
The proper way to do this is to implement a subset of JVMTI, but this
will do the job for now.

c8cc7d931b maintain a table to look up methods called via JNI
This simplifies the JNI implementation for looking up methods.  It also
fixes a bug where an applications calls GetStaticMethodID with class A
and then calls CallStatic<Type>Method with class B which extends A.  The
old code would look in the wrong method table and thus call the wrong
method.

0b79ab4fed fix race condition in compile function
1. Thread A calls function F, which needs to be compiled.  So it
compiles it.
 2. Thread B calls function F, sees that it's already been compiled and
so runs it.
 3. Thread B calls function G from function F, and G needs to be
compiled, but it needs to acquire the class lock first, which A owns.
 4. Thread A causes a GC, walks thread B's stack, but function F has not
yet been added to the method tree, so it thinks the stack has no frames.
 5. Thread A finally adds function F to the method tree.
 6. Thread A causes another GC and walks thread B's stack again, and
this time it finds function F in the method tree.

9fe00836f7 fix stack mapping code to do as many passes as necessary
Previously, we had been doing exactly two passes over the event log to
caculate the stack object reference map at each trace point.  It turns
out the correct number of passes depends on how many incorrect
assumptions we make about what the stack looks like at instructions with
multiple predecessors (i.e. targets of jumps and branches).

Each time we detect we've made one or more incorrect assumptions during
a pass, we must do another pass to correct those assumptions.  That pass
may in turn reveal further incorrect assumptions, and so on.

c1f3d28d24 Fixes dynamic symbol loading bug on Mac OS X.
On OS X, when you call dlopen() on a null library, and then call dlsym(),
the most recently loaded symbols are always used, no matter what flags
we seem to pass to dlopen().  The solution is to explicitly find the name
of the running executable, and open that as a library.

via mmap, which lets us map memory into the bottom 2GB of the address
