[LLVMdev] [PATCH] Capability of Win32.DLL with ENABLE_SHARED
Good summer, all! This patch enables ENABLE_SHARED=1 to build DLL based LLVM toolchain. I have checked this on Cygwin-1.5, Cygwin-1.7, mingw(msysgit) and mingw-cross-fedora12. I can separate this patch into some parts; cleanups, adding definitions and adding rules. Any feedbacks are welcome. Have fun! ...Takumi * Pros - reduction of linking time of toolchain. - capability of -load plugins on opt.exe - capability of LLVM APIs on lli.exe from bc - reduction of size of executables. * Cons - linking into DLL spends so much time. - contains some ugly tweaks. * Known issues - I took the way to link libstdc++.a together into LLVM.dll. It may invoke nasal demons. :( - On cygwin, fork(3) on DLL sometimes fails to clang.exe crashes. You have to do "rebaseall". (It would be better to get rid of fork(3) in llvm::System for cygwin in future) - I have not checked llvmc. * TODO - check system's stdc++.dll and use it with autoconf. -------------- next part -------------- diff --git a/Makefile.rules b/Makefile.rules index 66666b4..2a2128b 100644 --- a/Makefile.rules +++ b/Makefile.rules @@ -498,6 +498,25 @@ LLVMToolDir := $(LLVM_OBJ_ROOT)/$(BuildMode)/bin LLVMExmplDir:= $(LLVM_OBJ_ROOT)/$(BuildMode)/examples #-------------------------------------------------------------------- +# Locations of shared libraries +#-------------------------------------------------------------------- + +SharedPrefix := lib +SharedDir := $(LibDir) +LLVMSharedDir := $(LLVMLibDir) + +# Win32.DLL prefers to be located on the "PATH" of binaries. +ifeq ($(HOST_OS), $(filter $(HOST_OS), Cygwin MingW)) + SharedPrefix :+ SharedDir := $(ToolDir) + LLVMSharedDir := $(LLVMToolDir) +endif + +ifeq ($(HOST_OS),Cygwin) + SharedPrefix := cyg +endif + +#-------------------------------------------------------------------- # LLVM Capable Compiler #-------------------------------------------------------------------- @@ -570,12 +589,7 @@ ifeq ($(HOST_OS),Darwin) SharedLinkOptions += -mmacosx-version-min=$(DARWIN_VERSION) endif else -

Hi Takumi,> Any feedbacks are welcome. > Have fun!This seems to be pretty useful addition to LLVM on windows! And it seems the only painless way to make plugins working, yay! For me the patch looks pretty good. One minor thing: could you please rename SharedDir => SharedLibDir Thanks! -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

[LLVMdev] [PATCH] Capability of Win32.DLL with ENABLE_SHARED
Anton, Thanks for your comment. 2nd patch attached. - s/SharedDir/SharedLibDir/g - move prefix=cyg sunk into if(cygwin or mingw) arigato gozaimasu...Takumi * Additional issues - You may build LLVMHello.dll but I don't modify lib/Transforms/Makefile. Because making LLVMHello.dll requires the library LLVM.dll, but it oughta be on the way to making libs at building lib/Transforms/Hello. You can build LLVMHello.dll later; $ make -C lib/Transforms OPTIONAL_DIRS+=Hello * Why dummy bin/libstdc++.dll.a needed? - ld resolves data/bss symbols with *.a on LIBRARY_PATH, at next, resolves symbols with "auto-import" after. I had to suppress standard -lstdc++, it was the reason. 2010/8/5 Anton Korobeynikov <anton at korobeynikov.info>:> Hi Takumi, > >> Any feedbacks are welcome. >> Have fun! > This seems to be pretty useful addition to LLVM on windows!
