Doug Coleman 2a409c79e0 vm: Fix unused variable warnings on Windows. 2018-07-13 00:48:58 -05:00
Doug Coleman aa87e69d25 Revert "VM: removing the unused callstack-bounds primitive"
This reverts commit c55a6ef873.

This primitive is useful for fixing the macOS pthread bug and the javascriptcore library.

This fixes one part of the #452 bug.

Alexander Iljin 0d57734dab vm: replace block comments /**/ with line comments // 2016-09-09 05:47:52 +02:00
Björn Lindqvist 0274e889b9 VM: refactor tagged.hpp so it's not dependent on the factor_vm class
this way untag<byte_array>(relocation) can be used in code_blocks.hpp

Björn Lindqvist a53d5be683 VM: make allot_alien() and ffi_dlsym() use cell instead of void*
this way we get rid of a bunch of superfluous casts

Björn Lindqvist 59b7a50567 VM: removing the get_datastack/retainstack/callstack primitives
they can all be implemented using the
datastack/retainstack/callstack-for primitives and the less primitives
the better!

Björn Lindqvist 2b1c6ca11a VM: move the frame_predecessor() method to the code_heap class 2015-08-14 20:19:54 -07:00
John Benediktsson 4c2c8f133f vm: rename some primitives, and some cleanup.
* quot-compiled? => quotation-compiled?
* optimized? => word-optimized?

Björn Lindqvist 4bc0720e51 VM: more changes of structs to lambda functions 2015-07-06 22:49:38 +02:00
Björn Lindqvist fb9fa12cdd VM: change the definition of entry_point in word and quotation from void* to cell
this gets rid of lots of redundant casts from void* to cell
2015-01-15 09:29:13 +00:00
Björn Lindqvist af270cb4d8 VM converts the methods callstack::frame_top_at and code_block::offset to use cells instead of void*'s 2015-01-15 09:29:13 +00:00
Björn Lindqvist eb7a5ab1ba VM: some more fixing to make the types match better, converting void* to cell 2015-01-15 09:29:13 +00:00
Björn Lindqvist e47181e87a VM: change type of callstack_top and callstack_bottom from void* to cell
cell and void* is always the same size, but now you can remove lots of
redundant type casts from void* to cell.

Björn Lindqvist a6e191a490 VM: the frame_return_address and set_frame_return_address functions aren't needed (clearer to read/write the pointers directly) 2015-01-15 09:29:13 +00:00
Doug Coleman c675694619 vm: Annotate more places where we can gc.
Code formatting fix.

Doug Coleman 19685f4528 vm: jit::jit is a c++ constructor but it does not allocate objects to the Factor heaps.
Add annotations for gc allocating.

Erik Charlebois ffe41b3d7f VM: Fixup cast formatting after clang-format
clang-format doesn't recognize casts to non-pointer/non-template types
so it winds up adding a space between the right paren and the expression
and then failing to recognize prefix operators in the process
(e.g. foo = (cell) & bar; should be foo = (cell)&bar;). This commit
manually fixes up the major cases (fixnum, cell, all types ending in _t).

Joe Groff 0a1a252cdb vm: replace assert with FACTOR_ASSERT
Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.

Joe Groff 5d59faa7d1 vm: move dispatch_signal_handler to cpu-x86.cpp
The new signal handler dispatch is logic is CISC-centric; defer fixing it until we find someone who cares

Joe Groff 03ebb91170 vm: remove signal_from_leaf flag
Now that the resuming from the signal handler works within leaf procedures, the flag is no longer necessary.

Joe Groff 1386212d23 vm: dispatch signal handlers through subprimitive
We also need to save C ABI volatile registers before calling the signal handler in order to be able to reliably resume. Add signal-handler and leaf-signal-handler subprimitives to preserve volatile registers before invoking the signal handler C function.

Joe Groff 1dc31d133b vm: clean up signal handler dispatch
Remove the weird and broken functions fix_callstack_top and scrub_return_address. Instead, simply decrement the SP and store the PC from the front end of the signal handler so that the back end can return back into the original context normally. Currently aborts for leaf procedure frames pending a more robust solution.
