Daniel Dunbar 4d28366342 Don't try to build .bc version of libprofile if LLVMGCC isn't available.

Daniel Dunbar c2fdebe8af Remove cruft for installing runtime/ libraries directly into the LLVMGCCDIR; 
that is totally bogus.

Gordon Henriksen 6047b6e140 With this patch, the LowerGC transformation becomes the 
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)

Gordon Henriksen 0076a6727e GarbageCollection.html is expanded to encompass the coming

Anton Korobeynikov 3fc4a9f78a Dror GCCLibraries: they are obsolete since 2.0 release. This also reduces number of licenses used in LLVM.

 2007-01-07 18:13:48 +00:00
Reid Spencer 4b8067f37b Undo removal of the runtime libraries. While this may have been a bit 
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.

llvm-svn: 31807
 2006-11-17 03:32:33 +00:00
Reid Spencer 3f97d03f86 In LLVM 2.0 we won't use the runtime libraries as llvm-gcc3 support will 
be dropped. This patch pertains to removing the runtime directory from LLVM.

Reid Spencer 3056ebeb22 Remove unused variable. 
llvm-svn: 31404
 2006-11-03 01:58:30 +00:00
Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Reid Spencer a62f097c96 For PR786: 
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.

 2006-06-01 01:55:21 +00:00

 2006-06-01 01:49:08 +00:00
Reid Spencer a647c7ff42 Use archive libraries instead of object files for VMCore, BCReader, 
BCWriter, and bzip2 libraries. Adjust the various makefiles to accommodate
these changes. This was done to speed up link times.

llvm-svn: 28610
 2006-06-01 01:30:27 +00:00
Reid Spencer 6e64180f03 For PR786: 
Minor tweaks in public headers and a few .cpp files so that LLVM can build
successfully with -pedantic and projects using LLVM with -pedantic don't
get warnings from LLVM. There's still more -pedantic warnings to fix.

llvm-svn: 28453
 2006-05-24 19:21:13 +00:00
Reid Spencer 4873c79e41 Invert the tests on LLVMGCC_MAJVERS to check for value 4 instead of value 
3. This ensures that if llvm-gcc isn't available and consequently the value
of LLVMGCC_MAJVERS is blank, that the old (include runtime) behavior will
persist.

llvm-svn: 27464
 2006-04-06 22:15:51 +00:00
Reid Spencer 11dd4b9d9c For PR722: 
Change the check for llvm-gcc from using LLVMGCCDIR to LLVMGCC. This checks
for the actual tool rather than the directory in which the tool resides. In
the case of this bug, it is possible that the directory exists but that the
tools in that directory do not. This fix should avoid the makefile from
erroneously proceeding without the actual tools being available.

 2004-12-15 08:15:48 +00:00
Reid Spencer c6de5b56a3 Use the new BYTECODE_DESTINATION to override the default bytecode install 
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.
