2014-03-07Extend RTL API to support the LLVM backendYiannis Tsiouris
Extend the 'rtl_var' definition to host liveness information needed for a simple liveness analysis performed by the LLVM backend. Also, uncomment some function definitions (mostly simple accessors) that are already there and are useful for the translation of RTL code to LLVM assembly. Finally, extend the RTL 'call' instruction with the 'normalcontinuation' field which is required for translating calls that are in the scope of an exception handler. This extra field is required in order to point to a new basic block which will hold the 'unwind label' of LLVM's invoke instruction. While the 'unwind label' is semantically equivalent with the 'failcontinuation', in LLVM this block must have a 'landingpad' instruction. The problem arises by the fact that an RTL 'continuation' block can also be accessible by other paths in the RTL CFG, and so cannot be marked as a landing pad. To overcome this issue we create a new block (the 'normalcontinuation') which is used as the 'unwind label' of LLVM's invoke instruction and which will eventually transfer control to the 'continuation' block.

2013-03-10Fix handling of bs_match_string translationKostis Sagonas
Prior to R16B, the bs_match_string instruction worked only for cases that had a destination variable. As shown by the example below, this is not always the case and the Dst list can be empty. test(<<42, _/bits>> = B) -> B. This fixes a bug reported by Loïc Hoguin (02/12/2013); the original post used a different code example to illustrate the problem. While revising the code, a significant clean up was also performed.

With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.

2011-11-17hipe: Fix bug in hipe_rtl_lcm:calc_killed_expr_bbSverker Eriksson
Bug causing hipe to crash. Only provoked when changing the RTL generation for floating point operations. hipe_rtl:defines() was called with a expression ID instead of an expression. Use expr_id_map_get_expr() to get expression from ID. Need to pass along IdMap in order to do that.
2011-11-09erts,hipe: Limited support for hipe cross compilationSverker Eriksson
Normally hipe assumes that generated native code will be executed on the same emulator as the hipe compiler is running on. This commit allows you to build a hipe "cross-compiler" for a different configured emulator (but for same architecture). Example: > cd lib/hipe > make clean > make XCOMP=yes FLAVOR=smp TYPE=debug This hipe compiler will generate code to be executed on the debug compiled smp-emulator at $ERL_TOP.

2010-07-20One off-heap list, to eliminate two words per ETS object.Sverker Eriksson
Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object.
2010-02-03OTP-8323 Cross compilation improvements and other build systemRickard Green
improvements. Most notable: Lots of cross compilation improvements. The old cross compilation support was more or less non-existing as well as broken. Please, note that the cross compilation support should still be considered as experimental. Also note that old cross compilation configurations cannot be used without modifications. For more information on cross compiling Erlang/OTP see the $ERL_TOP/xcomp/README file. Support for staged install using <url href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed. For more information see the $ERL_TOP/README file. Documentation of the release target of the top Makefile. For more information see the $ERL_TOP/README file. make install now by default creates relative symbolic links instead of absolute ones. For more information see the $ERL_TOP/README file. $ERL_TOP/configure --help=recursive now works and prints help for all applications with configure scripts. Doing make install, or make release directly after make all no longer triggers miscellaneous rebuilds. Existing bootstrap system is now used when doing make install, or make release without a preceding make all. The crypto and ssl applications use the same runtime library path when dynamically linking against libssl.so and libcrypto.so. The runtime library search path has also been extended. The configure scripts of erl_interface and odbc now search for thread libraries and thread library quirks the same way as erts do. The configure script of the odbc application now also looks for odbc libraries in lib64 and lib/64 directories when building on a 64-bit system. The config.h.in file in the erl_interface application is now automatically generated in instead of statically updated which reduces the risk of configure tests without any effect.
