33580 2010-01-13 00:31:22 -0800 [BREWMP] Port currentThreadStackBase 2012-07-26 05:19:28 -0700 1 1 1 Unclassified WebKit JavaScriptCore 528+ (Nightly build) Other Other RESOLVED WONTFIX P2 Normal --- 33564 0 skyul webkit-unassigned beergun loki webkit.review.bot oldest_to_newest 180110 0 skyul 2010-01-13 00:31:22 -0800 IDEBUGGER_GetStackRange returns the initial address of the stack array. Because the stack grows downward, we can retrieve the stack base address by adding the stack size retrieved from IDEBUGGER_GetStackSize to the result of IDEBUGGER_GetStackRange. For BREW simulator, use WIN_OS currentThreadStackBase implementation as BREW simulator is essentially a Win32 program. 180111 1 46431 skyul 2010-01-13 00:34:05 -0800 Created attachment 46431 Port currentThreadStackBase to BREW 180113 2 webkit.review.bot 2010-01-13 00:38:45 -0800 Attachment 46431 did not pass style-queue: Failed to run "WebKitTools/Scripts/check-webkit-style" exit_code: 1 JavaScriptCore/runtime/Collector.cpp:551: Extra space before ( in function call [whitespace/parens] [4] Total errors found: 1 184765 3 46431 eric 2010-01-26 14:49:46 -0800 Comment on attachment 46431 Port currentThreadStackBase to BREW Wow, I would think creating/releasing some debugger object could be expensive. This function is called every time with garbage collect in JavaScriptCore. +#undef COMPILE_ASSERT problem, as mentioned in other bugs. 186948 4 skyul 2010-02-02 06:52:34 -0800 This is the place where the behavior differs between BREW and BREW MP. There is no IDebugger interface in BREW MP, so we can't use it to retrieve the stack base address. I am looking for a way to get it. 242341 5 59617 skyul 2010-06-24 00:06:06 -0700 Created attachment 59617 Patch There is no way to get the stack base address in Brew MP.

However, Brew MP does support preemptive multi-threading. It does not have threads, mutexs and thread-specific variables. I turned on ENABLE(SINGLE_THREADED) for Brew MP. 288312 9 skyul 2010-10-01 10:02:41 -0700 It seems we have a better way to find the stack base in Brew MP 1.1.0. For example, we can set the stack size and base in IThread2Util_CreateThread. Unfortunately, Brew MP 1.1.0 is not yet publicly available. 679184 10 skyul 2012-07-26 05:19:28 -0700 Brew MP port is no longer maintained. 46431 2010-01-13 00:34:05 -0800 2010-06-24 00:06:06 -0700
