2014-03-30Check for required LLVM version or issue errorYiannis Tsiouris
This checks that a required LLVM version (i.e. 3.4 or greater) appears in $PATH when 'to_llvm' flag is used; in case of failure, abort compilation with an error.
2014-03-07Support the LLVM backend in HiPEYiannis Tsiouris
Add flags to enable and use the LLVM backend: * to_llvm: use the LLVM pipeline for compilation (default optimization level is O3), * llvm_save_temps: save the intermediate files in current directory in order to be able to debug or optimize the LLVM assembly, * {to_llvm, O}: set the optimization level of LLVM opt and llc tools. Add some debug support to the loader; no semantic change intented.
2013-03-12Loosen the assumptions of code that handles escaping functionsKostis Sagonas
The HiPE compiler implicitly relied on the assumption that a function will never appear as both exported and also used as function closure. This was true because the BEAM compiler prior to R16B created module local anonymous functions for each closure. A proposed change to the BEAM compiler invalidates this invariant, so in order to accommodate for this change there needs to be a change of how the set of possibly escaping functions is computed. While doing this, the code was simplified by taking out a boolean() tag that indicated whether a function is a closure or exported and also slightly cleaned up the affected modules.

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.

2012-02-20Fix discrepancy in compile_infoKostis Sagonas
The BEAM disassembler used the atom 'none' to signify the absence of a compile_info chunk in a .beam file. This clashes with the type declaration of the compile_info field of a #beam_file{} record as containing a list. Use [] to signify the absence of this chunk. This simplifies the code and avoids a dialyzer warning. For fixing a similar problem and for consistency, changed also the return type of the attributes field of the #beam_file{} record. This required a change in the beam_disasm test suite.

2011-11-28hipe: Remove single function compilationBjörn Gustavsson
Compiling single functions (as opposed to whole modules) to native code complicates code management in HiPE. It would also vastly complicate whole-module optimizations, such as returning multiple return values instead of tuples within a module. As a first step, remove the external interface for the single compilation feature. In the future, there are many things that could be restructured and simplified.

2010-08-27Fix hipe:load/1Paul Guyot
hipe:load/1 (and unexported hipe:load/2) just did not work. Calling it would fail with a badmatch because only the hipe chunk was passed to do_load/3's third parameter called WholeModule. Since this parameter is then passed to beam_lib:all_chunks/1 which accepts the whole module as a binary as well as a path to the beam file, and since a path is exactly what we have in load/2, the fix consists in letting do_load/3 accept a path and passing it from load/2.
