2003-07-29* Stop hard-coding a value for beginning of emitted code on Sparc since we canMisha Brukman
now handle far calls (i.e., beyond the 30-bit limit in call instructions). * As a side-effect, this allows us to unify and clean up the mmap() call and code around it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7381 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-28Add rationale for the MAP_ANONYMOUS vs. MAP_ANON flags.Misha Brukman

2003-07-28Add ability for external C code to get pointers to functions given their name.Misha Brukman
This us used by bugpoint -- when code is compiled to a shared object to be JITted, it must use the JIT's lazy resolution method to find function addresses, because some functions will not be available at .so load time, as they are in the bytecode file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7363 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-02* If compiling on X86 or Sparc, automagically enable the JIT for that archMisha Brukman
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will force the inclusion of that JIT on a different architecture * If neither JIT is enabled (e.g., compiling on a different architecture), the -march option will not be available to LLI. * As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit faster by not including the x86 library. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7070 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-17Add #ifdef hack for MAP_ANONYMOUS being spelled MAP_ANON on some platforms.Brian Gaeke
(We're already talking about autoconf'ing this, so I'm assuming this hack will be short-lived...I just don't want it to get lost in my working files.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6761 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-06::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT :::Misha Brukman
The JIT is designed to code-generate a function at-a-time. That means that any pass can only make local changes to its function. Period. Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding globals to the Module, it cannot be run with the other passes, because by this time, the globals have been output already by the JIT, and the addresses of any globals appearing AFTER this point are not recognized. However, the PreSelection pass is a requirement for correctness in the Sparc codegen path, so it MUST be run. ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6650 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-06Removed debug print statement.Misha Brukman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6641 91177308-0d34-0410-b5e6-96231b3b80d8
2003-06-04* Institute a hack for the Sparc call to mmap() to get our generated code to beMisha Brukman
laid out closer to the VM so that calls to library functions (e.g. puts()) and callback (e.g. JITResolver::CompilationCallback) fit into 30 bits of the call instruction. * Abort if architecture is not yet supported (not X86 or Sparc) because it likely requires a different set of parameters to mmap() . * Stop using hard-coded values for page size; use sysconf(_SC_PAGESIZE) instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6610 91177308-0d34-0410-b5e6-96231b3b80d8
2003-06-04Sparc's dlsym() requires the special operand RTLD_SELF to find a symbol in theMisha Brukman
currently-running process. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6592 91177308-0d34-0410-b5e6-96231b3b80d8
2003-06-02* Removed SparcEmitter.cpp; rolled into lib/Target/Sparc/SparcV9CodeEmitter.cppMisha Brukman
* No more createX86Emitter() vs. createSparcEmitter() -- there can be only one * As a result, the memory management semantics must be handled according to platform -- the parameters to mmap() are particularly sensitive to the host architecture. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6527 91177308-0d34-0410-b5e6-96231b3b80d8

2003-05-28mmap() seems to be failing on Sparc, so just use malloc()/free() .Misha Brukman

2003-05-27Allow for specification of which JIT to run on the commandline.Misha Brukman
`lli -march=x86' or `lli -march=sparc' will forcefully select the JIT even on a different platform. Running lli without the -march option will select the JIT for the platform that it's currently running on. Pro: can test Sparc JIT (debug printing mode) on X86 -- faster to compile/link LLVM source base to test changes. Con: Linking lli on x86 now pulls in all the Sparc libs -> longer link time (but X86 can bear it, right?) In the future, perhaps this should be a ./configure option to enable/disable target JITting... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6360 91177308-0d34-0410-b5e6-96231b3b80d8
