Joe Groff 5f811c0573 vm: don't mask SIGTTIN from stdin_loop
Fixes #360
2011-11-08 08:42:48 -08:00
Joe Groff f9aa0419c4 vm: interrupt stdin_loop when entering fep
The stdin_loop thread will keep trying to consume input unless we stop it by sending it a signal. Use SIGUSR2 to stop the read syscall and a mutex to hold up the loop while the fep is active.

Joe Groff 04c6b2c393 vm: write signals to pipe immediately
The whole point is to wake up the mx without waiting for the next safepoint derp

Joe Groff 0e3c315099 vm: move bignum.cpp includes to master.hpp
That way they get PCHed

Joe Groff 18e01f7770 vm: enqueue signals for FEP signals too
Although SIGINT still can't interrupt the current Factor thread in a sane way, this will at least wake up the run loop when waiting for input and fix #348 when implemented at the application level.

Joe Groff b46fd5e655 GNUmakefile: use PCH so compiler goes faster
Also add more accurate dependencies on headers so "make" works right when headers change

Joe Groff 72d335f2b5 vm: write async signals to pipe for multiplexer
also factor out safepoint logic into its own file

Joe Groff 212d012cb1 vm: switch atomic::add to atomic::fetch_add
Win32 only provides fetch-and-add, not add-and-fetch, and we don't really care. Rename the functions so the order of operations is clear.

Joe Groff 3cad288f90 use gcc-4.2 on OS X 10.5, or clang on Xcode 4 2011-11-03 12:18:07 -07:00
Joe Groff 6bb46a3f1e vm: always generate safepoints in jit
Even if there's no stack frame we still need to safepoint before leaving the function. Fixes #332.

Joe Groff 92445d77e2 vm: restore sigaltstack setup on unix
#ifdef __OpenBSD__ is different from #ifndef __OpenBSD
2011-11-03 11:57:43 -07:00
Joe Groff d28845a1ef vm: reserve some more special-objects
Need a jit-safepoint object to deal with #332, and ffi-signal-handler words for immediate signal handling during FFI calls

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 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 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.
