!!! ATTENTION PSEH USERS - new features & a change in rules !!! modified include/reactos/libs/pseh/framebased.h modified include/reactos/libs/pseh/framebased/internal.h deleted include/reactos/libs/pseh/setjmp.h modified lib/pseh/framebased.c deleted lib/pseh/i386/setjmp.asm modified lib/pseh/pseh.rbuild Big PSEH revamp. If God is kind and merciful, this might be the last revision to PSEH ever !!! RULE CHANGE !!! Obsoleted _SEH_NO_NATIVE_NLG, do NOT use it anymore, it will now cause fatal compile-time errors !!! RULE CHANGE !!! As a side effect to the fix for a bug where a _SEH_TRY nested in a _SEH_HANDLE would lead to stack corruption, using "return" or "goto" from anywhere inside a PSEH block is now FORBIDDEN; all code that already did has been fixed in this revision !!! NEW FEATURE !!! To leave a PSEH block from anywhere inside it, use the new _SEH_YIELD(<statement>) macro; examples: _SEH_YIELD(return value), _SEH_YIELD(goto label), _SEH_YIELD(returnvalue = value; goto label); ALWAYS ensure a _SEH_YIELD() leads outside the top-level _SEH_TRY block - do NOT goto into an ancestor _SEH_TRY block!!! Also note that _SEH_YIELD() disables SEH protection for the enclosed statement, so do NOT perform operations that might throw exceptions inside a _SEH_YIELD(); finally, ensure the enclosed statement does NOT allow execution to continue, or _SEH_YIELD() will get in an infinite loop; bear with me, for I have done the impossible, so don't expect miracles Don't use a fake setjmp/longjmp *ever*, too dangerous; removed _SEHLongJmp & _SEHSetJmp, obsoleted _SEH_NO_NATIVE_NLG On GCC, use __builtin_setjmp/__builtin_longjmp instead of setjmp/longjmp; they produce efficient code that plays well with optimizations, require no external library and are designed specifically for exception handling; should result in faster code and no hidden bugs Use inline code to enter/leave trylevels; yields much better binary code Inline handlers inside _SEH_PortableFrame_t instead of pointing to them; yields better code for the most common usages Turn all top-level statements generated by macros from bare scopes into for loops, to ensure they are used correctly as stand-alone statements Removed bitrotten old syntax, because it wasn't being used nor maintained modified dll/3rdparty/freetype/freetype.rbuild modified dll/win32/kernel32/kernel32.rbuild modified drivers/network/tcpip/tcpip.rbuild modified lib/drivers/ip/ip.rbuild modified lib/rtl/rtl.rbuild modified ntoskrnl/ntoskrnl.rbuild modified subsystems/win32/win32k/win32k.rbuild Removed obsolete _SEH_NO_NATIVE_NLG define modified drivers/network/afd/afd/lock.c modified drivers/network/afd/afd/tdi.c modified subsystems/csr/csrsrv/api.c modified subsystems/win32/win32k/ntuser/clipboard.c modified subsystems/win32/win32k/ntuser/window.c Use the new _SEH_YIELD macro to return/goto from SEH blocks modified tools/rbuild/backend/mingw/modulehandler.cpp modified tools/rbuild/backend/mingw/modulehandler.h modified tools/rbuild/module.cpp modified tools/rbuild/project.dtd modified tools/rbuild/rbuild.h Don't use the obsolete _SEH_NO_NATIVE_NLG flag anymore Only add underscores to imported symbols when module is marked underscoresymbols="true"; fixes debugsup and, indirectly, PSEH tracing modified lib/3rdparty/mingw/mingw.rbuild Build with underscoresymbols="true" svn path=/trunk/; revision=26224 |
