2010-05-06Overhauled llvm/clang docs builds. Closes PR6613.mike-m
NOTE: 2nd part changeset for cfe trunk to follow. *** PRE-PATCH ISSUES ADDRESSED - clang api docs fail build from objdir - clang/llvm api docs collide in install PREFIX/ - clang/llvm main docs collide in install - clang/llvm main docs have full of hard coded destination assumptions and make use of absolute root in static html files; namely CommandGuide tools hard codes a website destination for cross references and some html cross references assume website root paths *** IMPROVEMENTS - bumped Doxygen from 1.4.x -> 1.6.3 - splits llvm/clang docs into 'main' and 'api' (doxygen) build trees - provide consistent, reliable doc builds for both main+api docs - support buid vs. install vs. website intentions - support objdir builds - document targets with 'make help' - correct clean and uninstall operations - use recursive dir delete only where absolutely necessary - added call function fn.RMRF which safeguards against botched 'rm -rf'; if any target (or any variable is evaluated) which attempts to remove any dirs which match a hard-coded 'safelist', a verbose error will be printed and make will error-stop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103213 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-28Update of 94055 to track the IR level call site information via an intrinsic.Jim Grosbach
This allows code gen and the exception table writer to cooperate to make sure landing pads are associated with the correct invoke locations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94726 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-14I don't see any point in having both eh.selector.i32 and eh.selector.i64,Duncan Sands
so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector. Likewise for eh.typeid.for. This aligns us with gcc, which always uses a 32 bit value for the selector on all platforms. My understanding is that the register allocator used to assert if the selector intrinsic size didn't match the pointer size, and this was the reason for introducing the two variants. However my testing shows that this is no longer the case (I fixed some bugs in selector lowering yesterday, and some more today in the fastisel path; these might have caused the original problems). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-11SjLj based exception handling unwinding support. This patch is nasty, brutishJim Grosbach
and short. Well, it's kinda short. Definitely nasty and brutish. The front-end generates the register/unregister calls into the SjLj runtime, call-site indices and landing pad dispatch. The back end fills in the LSDA with the call-site information provided by the front end. Catch blocks are not yet implemented. Built on Darwin and verified no llvm-core "make check" regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78625 91177308-0d34-0410-b5e6-96231b3b80d8

llvm.eh.sjlj.* for better clarity as to their purpose and scope. Add a description of llvm.eh.sjlj.setjmp to ExceptionHandling.html.

needed, because they just "mark" register liveins and we let frontend solve type issue, not lowering code :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41763 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-27There is an impedance matching problem between LLVM andDuncan Sands
gcc exception handling: if an exception unwinds through an invoke, then execution must branch to the invoke's unwind target. We previously tried to enforce this by appending a cleanup action to every selector, however this does not always work correctly due to an optimization in the C++ unwinding runtime: if only cleanups would be run while unwinding an exception, then the program just terminates without actually executing the cleanups, as invoke semantics would require. I was hoping this wouldn't be a problem, but in fact it turns out to be the cause of all the remaining failures in the LLVM testsuite (these also fail with -enable-correct-eh-support, so turning on -enable-eh didn't make things worse!). Instead we need to append a full-blown catch-all to the end of each selector. The correct way of doing this depends on the personality function, i.e. it is language dependent, so can only be done by gcc. Thus this patch which generalizes the eh.selector intrinsic so that it can handle all possible kinds of action table entries (before it didn't accomodate cleanups): now 0 indicates a cleanup, and filters have to be specified using the number of type infos plus one rather than the number of type infos. Related gcc patches will cause Ada to pass a cleanup (0) to force the selector to always fire, while C++ will use a C++ catch-all (null). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41484 91177308-0d34-0410-b5e6-96231b3b80d8
