Joe Groff 1351e30e52 vm: sampling profiler timer for windows 
Spawn a thread and have it spin on the performance counter, triggering safepoints on the main thread every sample time

Joe Groff 981862f35e Revert "syntax: make it so PRIMITIVE: verifies primitives" 
This reverts commit 200ea70cffc4bdc74a97e4981442161f64cdbaa3.

Joe Groff 125c46c10f vm: stub out windows sampling timer implementation 
AFAIK Windows has no equivalent to setitimer. We'll probably need to use a thread that periodically pauses and samples the main VM thread.

Joe Groff f5cdfaeb2a vm: count samples from foreign threads 
On OS X it appears the mach exception thread and libdispatch queue threads occasionally get the SIGALRM from the itimer. Count those as foreign_thread_samples instead of letting the signal kill the process.

Joe Groff 27d7e4af53 vm: actually collect samples and add primitives... 2011-11-02 13:23:10 -07:00
Joe Groff 5b6fb25ffd add sampling profiler primitives for bootstrap 2011-11-02 13:23:10 -07:00
Joe Groff c0b26a2781 syntax: make it so PRIMITIVE: verifies primitives 
It's a bit strange for disparate vocabs to reference words that get created out of thin air during bootstrap, so this lets there be some trace in the seeded vocab source that there was a word created there.

Joe Groff 9f6f36fdec cpu.x86.bootstrap: simplify leaf-signal-handler 
We can use RET (stack-frame-size - cell) instead of doing stack gymnastics.

Joe Groff 40bc8459db vm: bottom_frame method for contexts 
ctx->callstack_bottom - 1 -- the fuck does that mean?!
 2011-11-02 13:23:07 -07:00
Joe Groff be5c7476d7 vm: don't allocate callstack samples on data heap 
Invoking a GC during a safepoint has some complications, so stuff the callstack samples in a vector instead.
 2011-11-02 13:23:07 -07:00
Joe Groff b341b0ce13 vm: only show factorbug basic commands at first 
"help" brings up the entire command list.
 2011-11-02 13:23:07 -07:00
Joe Groff 80fb7788d9 vm: groundwork for sampling profiler 
Set up the state necessary to collect samples. We still need to add GC support for walking the sample set, and the compiler needs to register GC roots before safepoints as well. We also need primitives to expose the data to Factor for reporting.
