Sami Vaarala	a9fa2362ec	Rework value stack grow/shrink, lazy shrink * Make value stack and call stack limits configurable via DUK_USE_xxx options. Also make value stack grow/shrink constants configurable. * Rewrite value stack grow/shrink check primitives for better hot/cold path handling. * Use a proportional spare for grow and shrink sizes so that applications needing a large value stack have fewer value stack resizes. * Grow value stack allocation when entering a call or when explicitly requested via e.g. duk_require_stack(). * Never shrink the value stack when entering a call, so that the unwind path is guaranteed to have value stack to handle a protected call return. This guarantee is only needed for protected call but is now applied to all calls for simplicity. * Don't perform a value stack shrink check at all in function return anymore. It would be OK from protected call semantics perspective to do a shrink attempt without throwing if it fails. * Perform a value stack shrink check in mark-and-sweep only for now. When emergency GC is running, shrink to a minimal size respecting current value stack reserve.	8 years ago

Sami Vaarala	96d301b3cb	Rename src/ to src-input/ to match dist With this change the directory naming in the main repo and dist is the same.	8 years ago
Sami Vaarala	36494812ed	ENC16/DEC16/EXTSTR udata changes Also remove mostly unused old debug code. Debug code doesn't have access to 'heap' so it cannot decode pointers. Cause an #error for now if both debug prints and pointer compression are enabled at the same time. Remove duk_debug_hobject.c from make and dist. It was out of date and not used in practice anymore.	10 years ago

Sami Vaarala	2ef85f296e	Remove (#if 0) unused functions These were revealed after fixing DUK_SINGLE_FILE, gcc will complain about these internal functions being declared, defined, but not used. There were also a few declared functions that did not exist. Compiled binary size was reduced by a few kilobytes! Unused functions must be commented out carefully: some functions might be used with certain feature options but not by the defaults. These removals were verified with grep. There are no call sites for DUK_DEBUG_DUMP_HEAP() so all the functions in duk_debug_heap.c are unused, even with a debug build. Out of the checked allocation macros, only DUK_REALLOC_INDIRECT_CHECKED() is actually in use at the moment. This commit just comments the unused stuff out, but it might be better to just remove the unused stuff entirely.	10 years ago
Sami Vaarala	966c0fa511	Realloc fixes to heap memory handling Discovered with GC torture testing: when mark-and-sweep is triggered during a realloc, the realloc() retry handler does not handle zero size correctly (i.e. it doesn't accept a NULL as a successful result in that case). After these fixes GC torture tests pass.	10 years ago

Sami Vaarala	f8423ffb36	Format string cleanups, allow NULL+%s/%p in debug Lots of minor string format cleanups (casts mainly). Add a special check to detect NULL pointers with %s/%p formats in debug logging to avoid calling the platform sprintf() with a NULL value. This is especially important for %s + NULL, which is not portable and may crash on some platforms. Debug logging will now format these specially as "NULL" and avoid calling the platform for formatting, so debug log call sites don't need to be careful with NULL pointers any more.	10 years ago
