* Add rationale for the MAP_ANONYMOUS vs. MAP_ANON flags.Misha Brukman2003-07-281-0/+1

* Add ability for external C code to get pointers to functions given their name.Misha Brukman2003-07-281-3/+15
| | | | | | | | | 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. llvm-svn: 7363

| | | | | | | | | | | | | | | | | 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 ::: llvm-svn: 6650

* Allow for specification of which JIT to run on the commandline.Misha Brukman2003-05-274-13/+269
| | | | | | | | | | | | | | | | `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... llvm-svn: 6360
