Doug Coleman 5813e8384e command-line.startup: document more command line flags. we already have -nosignals, but it was hidden in the source code. Fix spacing for default image. Closes #1514. 2016-03-03 17:16:39 -08:00
Doug Coleman 67eb64cf00 vm/contexts.cpp: We are only deleting half the contexts because we increment the iter twice per loop! Fixes #1534. Thanks clang! 2016-03-01 00:19:43 -08:00
Björn Lindqvist 44b9b26baa VM: nitpick fix of filenames in comments 2016-02-28 01:23:59 +01:00
Björn Lindqvist 2db1e7e6a5 VM: simplifies factor_vm::determine_inline_cache_type 2016-02-28 01:10:12 +01:00
Björn Lindqvist 0c9c0b2f82 VM: removes a few methods related to relocation handling
They are only used once, so it is simpler to "inline" them

Björn Lindqvist 7da72ac77c VM: the compute_vm_address method can be removed 2015-12-13 13:56:36 +01:00
Björn Lindqvist 08766090d3 VM: more fine-grained control over which special objects to save
It removes a few roots that doesn't need to be saved in the image and
can save a few hundred bytes.

Björn Lindqvist 46bfcbf3a2 VM: the rel_type() and rel_offset() accessors in instruction_operand can be removed 2015-12-13 13:56:36 +01:00
Björn Lindqvist 1a72f731e0 VM: now special-objects is used for -1, 0, 1 and t
The fields in the image_header aren't read or written to but I haven't
changed the format yet.

Björn Lindqvist 339b1b6466 VM: put the singletons t, -1, 0 and 1 in the special objects table
Having them there instead of as fields in the vm struct removes a bunch
of special handling. This commit just adds them and doesn't remove the
old ones to avoid potential chicken-and-egg bootstrap problems.

Björn Lindqvist d911bc45fd VM: refactors the prepare_boot_image method
easier to read if the methods compile_all_words and
initialize_all_quotations which are only used once are "inlined"
2015-12-04 13:57:57 +01:00
Björn Lindqvist 867c85f1c5 VM: can't go through the accessor here because it triggers the assert 2015-11-25 18:12:55 +01:00
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
2015-11-24 16:00:50 +01:00
Björn Lindqvist 22bb0cfecf VM: fixes to use the TAG macro over tagged<object>(obj).type() 2015-11-23 02:27:22 +01:00
Björn Lindqvist a8aaa42882 VM: refactoring to use the TAG macro directly over the tagged struct
eg. TAG(obj) is equivalent to tagged<object>(obj).type()
2015-11-22 23:42:54 +01:00
Björn Lindqvist 575da3e478 VM: fix so that errno is set if MoveFileEx fails, should fix #1490 2015-10-12 12:19:21 +02:00
Björn Lindqvist 7dfb352a7e VM: replaced calls to out_of_memory() with fatal_error()
No need for a special out of memory function -- it's just a kind of
fatal  error. Also make fatal_error() call dump_memory_layout() for
easier debugging.

Björn Lindqvist cb55fcf20f VM: prettier and more detailed output when dumping generations 2015-10-08 16:25:35 +02:00
Doug Coleman 7eec8621aa vm: MoveFileEx returns BOOL which needs help converting to C++ bool. 2015-10-01 17:04:13 +00:00
John Benediktsson bd04290187 vm: fix signature for safe_fopen. 2015-09-30 19:03:39 -07:00
Björn Lindqvist 85784c5265 VM: make save-image throw exception on error (#1090) 2015-09-30 23:31:47 +02:00
Björn Lindqvist 2536b6cd93 VM: fix move_file called from save_image
save_image() shouldn't throw exceptions because if the 'then_die'
argument is t it would leave factor in an inconsistent state. So
therefore move_file() should be fixed and raw_fclose() called instead of
safe_fclose().

Björn Lindqvist 40eb664425 VM: simplified save_image, goto works here! 2015-09-29 23:13:09 +02:00
Björn Lindqvist ffc441ad63 VM: looks like ERROR_C_STRING is never thrown, so it can be removed 2015-09-29 23:12:56 +02:00
Björn Lindqvist 614595bd9a VM: workhorse attribute not used 2015-09-22 08:51:03 +02:00
Björn Lindqvist b3de115e3c VM: remove RT_EXCEPTION_HANDLER reference 2015-09-02 21:54:47 +02:00
Björn Lindqvist 769c09def5 VM: for consistency, it is easier to put all functions in the exports file 2015-09-02 21:54:44 +02:00
Björn Lindqvist bc7f9ee669 VM: always use undecorated names when loading ffi functions
For win32, Factor tries four different function names when loading
stdcall and fastcall functions, in case decorated names are used in the
dll. It seems to not be necessary because a dll meant for 3rd party use
will always export undecorated
names (http://blogs.msdn.com/b/oldnewthing/archive/2004/01/12/57833.aspx).

Björn Lindqvist da3de080ee VM: callback_entry_point() and update() can be removed 2015-09-02 21:54:39 +02:00
Björn Lindqvist de4917e6a1 VM: give the exception handling special object a real name 2015-09-02 21:54:33 +02:00
Björn Lindqvist 22887c5816 VM: get rid of the odd RT_EXCEPTION_HANDLER relocation
The address to the win32 relocation handler can be stored in a special
object and be accessed by jit-install-seh. Doing it that way is better
because you can remove a lot of special code related to that relocation
type.

Björn Lindqvist 68c0c0f53a VM: clear commented out code 2015-09-02 21:54:27 +02:00
Björn Lindqvist 84ec2164c2 VM: nicer way of initializing those special objects that are aliens 2015-09-02 21:54:18 +02:00
Björn Lindqvist cee0b19324 VM: the ffi-signal-handler and ffi-leaf-signal-handler primitives are unused 2015-09-02 21:54:15 +02:00
Björn Lindqvist a9c33cbfd7 VM: better way to set signal_resumable 2015-08-26 20:23:28 +02:00
Björn Lindqvist 663e5e2a09 VM: fix jit-signal-handler-prolog/epilog to account for the home space
Windows 64bit abi requires callers to reserve 32 bytes of home space in
the stack frame which the callee is free to clobber. Previous versions
of VS didn't compile code to take advantage of the home space so it
worked fined. VS2015 however, is using the home space which causes
registers and flags that were supposed to be saved to be
overwritten. The fix is to put a little extra empty space at the bottom
of the stack frame.

Björn Lindqvist 316b16f377 VM: instead of enqueue_safepoint() just call set_safepoint_guard() directly 2015-08-26 20:23:23 +02:00
Björn Lindqvist 5a39631b4b VM: refactoring, new function get_thread_pc() and simpler logic in exception_handler() 2015-08-26 20:23:20 +02:00
Björn Lindqvist 2a852915d2 VM: signal_fault_pc probably should be set here... 2015-08-26 20:23:17 +02:00
Björn Lindqvist 10464e7e4e VM: LEAF_FRAME_SIZE is 16 bytes on all platforms so we can simplify it 2015-08-26 20:23:15 +02:00
Björn Lindqvist cb0bf3b1ce VM: merge memory_protection_error() with memory_signal_handler_impl() 2015-08-24 07:23:40 -07:00
Björn Lindqvist 39c888230a VM: new function set_safepoint_guard to replace the functions (un)guard_safepoint 2015-08-24 07:23:40 -07:00
Björn Lindqvist 56ddb59b00 VM: new function set_memory_locked(true/false)
it wraps the mprotect/VirtualProtect platform differences and makes it
so you can unify some windows/unix code path forks
2015-08-24 07:23:40 -07:00
Björn Lindqvist 94eb855903 VM: make the debug output a little prettier 2015-08-24 07:23:40 -07:00
Björn Lindqvist 51daaf6be4 VM: the windows_image_path method is unused 2015-08-24 07:23:40 -07:00
Björn Lindqvist 4efef7bfd9 VM: merge the compute_dlsym_toc_address() with the
compute_dlsym_address() method

it makes the code slightly more cluttered but you get rid of a lot of
special casing for the ppc platform
2015-08-23 18:36:31 -07:00
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
2015-08-23 18:36:31 -07:00
Björn Lindqvist 1045f41778 VM: gc required here because we are iterating all objects 2015-08-23 18:36:31 -07:00
Björn Lindqvist 7f545271f4 VM: new iteration method each_object_each_slot()
used by find_data_references() and dump_edges() instead of the functor structs
2015-08-23 18:36:31 -07:00
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!
