2008-01-07With this patch, the LowerGC transformation becomes theGordon Henriksen
ShadowStackCollector, which additionally has reduced overhead with no sacrifice in portability. Considering a function @fun with 8 loop-local roots, ShadowStackCollector introduces the following overhead (x86): ; shadowstack prologue movl L_llvm_gc_root_chain$non_lazy_ptr, %eax movl (%eax), %ecx movl $___gc_fun, 20(%esp) movl $0, 24(%esp) movl $0, 28(%esp) movl $0, 32(%esp) movl $0, 36(%esp) movl $0, 40(%esp) movl $0, 44(%esp) movl $0, 48(%esp) movl $0, 52(%esp) movl %ecx, 16(%esp) leal 16(%esp), %ecx movl %ecx, (%eax) ; shadowstack loop overhead (none) ; shadowstack epilogue movl 48(%esp), %edx movl %edx, (%ecx) ; shadowstack metadata .align 3 ___gc_fun: # __gc_fun .long 8 .space 4 In comparison to LowerGC: ; lowergc prologue movl L_llvm_gc_root_chain$non_lazy_ptr, %eax movl (%eax), %ecx movl %ecx, 48(%esp) movl $8, 52(%esp) movl $0, 60(%esp) movl $0, 56(%esp) movl $0, 68(%esp) movl $0, 64(%esp) movl $0, 76(%esp) movl $0, 72(%esp) movl $0, 84(%esp) movl $0, 80(%esp) movl $0, 92(%esp) movl $0, 88(%esp) movl $0, 100(%esp) movl $0, 96(%esp) movl $0, 108(%esp) movl $0, 104(%esp) movl $0, 116(%esp) movl $0, 112(%esp) ; lowergc loop overhead leal 44(%esp), %eax movl %eax, 56(%esp) leal 40(%esp), %eax movl %eax, 64(%esp) leal 36(%esp), %eax movl %eax, 72(%esp) leal 32(%esp), %eax movl %eax, 80(%esp) leal 28(%esp), %eax movl %eax, 88(%esp) leal 24(%esp), %eax movl %eax, 96(%esp) leal 20(%esp), %eax movl %eax, 104(%esp) leal 16(%esp), %eax movl %eax, 112(%esp) ; lowergc epilogue movl 48(%esp), %edx movl %edx, (%ecx) ; lowergc metadata (none) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45670 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-27GarbageCollection.html is expanded to encompass the comingGordon Henriksen

2006-11-17Undo removal of the runtime libraries. While this may have been a bitReid Spencer
premature, these libraries will be going away for the 2.0 release. Other arrangements for profiling, gc, etc. should be made in the next few months. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31807 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-16In LLVM 2.0 we won't use the runtime libraries as llvm-gcc3 support willReid Spencer
be dropped. This patch pertains to removing the runtime directory from LLVM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31793 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-01Use archive libraries instead of object files for VMCore, BCReader,Reid Spencer
BCWriter, and bzip2 libraries. Adjust the various makefiles to accommodate these changes. This was done to speed up link times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28610 91177308-0d34-0410-b5e6-96231b3b80d8

2004-12-13Use the new BYTECODE_DESTINATION to override the default bytecode installReid Spencer
destination for this library so that it goes to $(cferuntime_libdir) rather than just $(libdir). Normal bytecode libraries should be installed in the $(libdir), but these ones are "special" because they're part of the the C/C++ front end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18882 91177308-0d34-0410-b5e6-96231b3b80d8
