The output bitcode file can be -another bitcode file or an executable bitcode program. Using additional -options, \fBllvm-ld\fR is able to produce native code executables. -.PP -The \fBllvm-ld\fR tool is the main linker for \s-1LLVM\s0. It is used to link together -the output of \s-1LLVM\s0 front-end compilers and run \*(L"link time\*(R" optimizations (mostly -the inter-procedural kind). -.PP -The \fBllvm-ld\fR tools attempts to mimic the interface provided by the default -system linker so that it can act as a \fIdrop-in\fR replacement. -.SS "Search Order" -.IX Subsection "Search Order" -When looking for objects specified on the command line, \fBllvm-ld\fR will search -for the object first in the current directory and then in the directory -specified by the \fB\s-1LLVM_LIB_SEARCH_PATH\s0\fR environment variable. If it cannot -find the object, it fails. -.PP -When looking for a library specified with the \fB\-l\fR option, \fBllvm-ld\fR first -attempts to load a file with that name from the current directory. If that -fails, it looks for lib\fIlibrary\fR.bc, lib\fIlibrary\fR.a, or lib\fIlibrary\fR.\fIshared -library extension\fR, in that order, in each directory added to the library search -path with the \fB\-L\fR option. These directories are searched in the order they -are specified. If the library cannot be located, then \fBllvm-ld\fR looks in the -directory specified by the \fB\s-1LLVM_LIB_SEARCH_PATH\s0\fR environment variable. If it -does not find a library there, it fails. -.PP -The \fIshared library extension\fR may be \fI.so\fR, \fI.dyld\fR, \fI.dll\fR, or something -different, depending upon the system. -.PP -The \fB\-L\fR option is global. It does not matter where it is specified in the -list of command line arguments; the directory is simply added to the search path -and is applied to all libraries, preceding or succeeding, in the command line. -.SS "Link order" -.IX Subsection "Link order" -All object and bitcode files are linked first in the order they were -specified on the command line. All library files are linked next. -Some libraries may not be linked into the object program; see below. -.SS "Library Linkage" -.IX Subsection "Library Linkage" -Object files and static bitcode objects are always linked into the output -file. Library archives (.a files) load only the objects within the archive -that define symbols needed by the output file. Hence, libraries should be -listed after the object files and libraries which need them; otherwise, the -library may not be linked in, and the dependent library will not have its -undefined symbols defined. -.SS "Native code generation" -.IX Subsection "Native code generation" -The \fBllvm-ld\fR program has limited support for native code generation, when -using the \fB\-native\fR or \fB\-native\-cbe\fR options. Native code generation is -performed by converting the linked bitcode into native assembly (.s) or C code -and running the system compiler (typically gcc) on the result. -.SH "OPTIONS" -.IX Header "OPTIONS" -.SS "General Options" -.IX Subsection "General Options" -.IP "\fB\-help\fR" 4 -.IX Item "-help" -Print a summary of command line options. -.IP "\fB\-v\fR" 4 -.IX Item "-v" -Specifies verbose mode. In this mode the linker will print additional -information about the actions it takes, programs it executes, etc. -.IP "\fB\-stats\fR" 4 -.IX Item "-stats" -Print statistics. -.IP "\fB\-time\-passes\fR" 4 -.IX Item "-time-passes" -Record the amount of time needed for each pass and print it to standard -error. -.SS "Input/Output Options" -.IX Subsection "Input/Output Options" -.IP "\fB\-o\fR \fIfilename\fR" 4 -.IX Item "-o filename" -This overrides the default output file and specifies the name of the file that -should be generated by the linker. By default, \fBllvm-ld\fR generates a file named -\&\fIa.out\fR for compatibility with \fBld\fR. The output will be written to -\&\fIfilename\fR. -.IP "\fB\-b\fR \fIfilename\fR" 4 -.IX Item "-b filename" -This option can be used to override the output bitcode file name. By default, -the name of the bitcode output file is one more \*(L".bc\*(R" suffix added to the name -specified by \fB\-o filename\fR option. -.IP "\fB\-l\fR\fIname\fR" 4 -.IX Item "-lname" -This option specifies the \fIname\fR of a library to search when resolving symbols -for the program. Only the base name should be specified as \fIname\fR, without a -\&\fIlib\fR prefix or any suffix. -.IP "\fB\-L\fR\fIPath\fR" 4 -.IX Item "-LPath" -This option tells \fBllvm-ld\fR to look in \fIPath\fR to find any library subsequently -specified with the \fB\-l\fR option. The paths will be searched in the order in -which they are specified on the command line. If the library is still not found, -a small set of system specific directories will also be searched. Note that -libraries specified with the \fB\-l\fR option that occur \fIbefore\fR any \fB\-L\fR options -will not search the paths given by the \fB\-L\fR options following it. -.IP "\fB\-link\-as\-library\fR" 4 -.IX Item "-link-as-library" -Link the bitcode files together as a library, not an executable. In this mode, -undefined symbols will be permitted. -.IP "\fB\-r\fR" 4 -.IX Item "-r" -An alias for \-link\-as\-library. -.IP "\fB\-native\fR" 4 -.IX Item "-native" -Generate a native machine code executable. -.Sp -When generating native executables, \fBllvm-ld\fR first checks for a bitcode -version of the library and links it in, if necessary. If the library is -missing, \fBllvm-ld\fR skips it. Then, \fBllvm-ld\fR links in the same -libraries as native code. -.Sp -In this way, \fBllvm-ld\fR should be able to link in optimized bitcode -subsets of common libraries and then link in any part of the library that -hasn't been converted to bitcode. -.IP "\fB\-native\-cbe\fR" 4 -.IX Item "-native-cbe" -Generate a native machine code executable with the \s-1LLVM\s0 C backend. -.Sp -This option is identical to the \fB\-native\fR option, but uses the -C backend to generate code for the program instead of an \s-1LLVM\s0 native -code generator. -.SS "Optimization Options" -.IX Subsection "Optimization Options" -.IP "\fB\-disable\-inlining\fR" 4 -.IX Item "-disable-inlining" -Do not run the inlining pass. Functions will not be inlined into other -functions. -.IP "\fB\-disable\-opt\fR" 4 -.IX Item "-disable-opt" -Completely disable optimization. -.IP "\fB\-disable\-internalize\fR" 4 -.IX Item "-disable-internalize" -Do not mark all symbols as internal. -.IP "\fB\-verify\-each\fR" 4 -.IX Item "-verify-each" -Run the verification pass after each of the passes to verify intermediate -results. -.IP "\fB\-strip\-all\fR" 4 -.IX Item "-strip-all" -Strip all debug and symbol information from the executable to make it smaller. -.IP "\fB\-strip\-debug\fR" 4 -.IX Item "-strip-debug" -Strip all debug information from the executable to make it smaller. -.IP "\fB\-s\fR" 4 -.IX Item "-s" -An alias for \fB\-strip\-all\fR. -.IP "\fB\-S\fR" 4 -.IX Item "-S" -An alias for \fB\-strip\-debug\fR. -.IP "\fB\-export\-dynamic\fR" 4 -.IX Item "-export-dynamic" -An alias for \fB\-disable\-internalize\fR -.IP "\fB\-post\-link\-opt\fR\fIPath\fR" 4 -.IX Item "-post-link-optPath" -Run post-link optimization program. After linking is completed a bitcode file -will be generated. It will be passed to the program specified by \fIPath\fR as the -first argument. The second argument to the program will be the name of a -temporary file into which the program should place its optimized output. For -example, the \*(L"no-op optimization\*(R" would be a simple shell script: -.Sp -.Vb 2 -\& #!/bin/bash -\& cp $1 $2 -.Ve -.SH "EXIT STATUS" -.IX Header "EXIT STATUS" -If \fBllvm-ld\fR succeeds, it will exit with 0 return code. If an error occurs, -it will exit with a non-zero return code. -.SH "ENVIRONMENT" -.IX Header "ENVIRONMENT" -The \f(CW\*(C`LLVM_LIB_SEARCH_PATH\*(C'\fR environment variable is used to find bitcode -libraries. Any paths specified in this variable will be searched after the \f(CW\*(C`\-L\*(C'\fR -options. -.SH "SEE ALSO" -.IX Header "SEE ALSO" -llvm-link -.SH "AUTHORS" -.IX Header "AUTHORS" -Maintained by the \s-1LLVM\s0 Team (<http://llvm.org/>). |
