2010-05-20Remove the bs_bits_to_bytes/3 instructionBjörn Gustavsson
The last compiler to generate code that uses the bs_bits_to_bytes/3 instruction was the R11 compiler. Since we don't support loading R11 *.beam files in R14, removing the remaining support for the instruction.
2010-05-20Cover handling of 'math' BIFsBjörn Gustavsson
Extend float_SUITE to cover the handling of all BIFs in the 'math' module. This change will increase test coverage of erl_bifs and erl_type.
2010-05-20beam_bool: Remove a clause in live_regs/1 that cannot matchBjörn Gustavsson
live_regs/1 folds over a list of tuples, so a clause matching an element being an empty list can never match. If the list for some unfathomable reason would contain an empty list, there will be an internal compiler error and no *.beam file will be created. Thus this change is safe.
2010-05-20beam_bool: Cover handling of bs_context_to_binary in initialized_regs/2Björn Gustavsson
Add a test case (derived from dets_v9:scan_skip/8), to cover the clause in initialized_regs/2 that handles bs_context_to_binary.
2010-05-20beam_bool: Remove a clause in initialized_regs/2 that cannot matchBjörn Gustavsson
When scanning a reversed instruction sequence for a function, it is impossible to reach the end of the list, because each function must have a fun_info/4 instruction followed by a label/1 instruction at the beginning, and there is a clause that will handle those instructions. If for some unfathomable reason the end of the list would be reached, with this change there will be an internal compiler error and no *.beam file will be created. Thus this change is safe.
2010-05-20beam_block: Remove a clause that will never be executedBjörn Gustavsson
Since the introduction of literals in R12B, empty tuples are literals. Thus the put_tuple/2 instruction is always followed by at least one put/1 instruction. Therefore the alloc_may_pass/1 function in beam_block no longer needs a clause for for "put_tuple", because the clause for "put" will always be reached first (since the instruction stream is scanned in reverse execution order). Note that if the compiler would generate a "put_tuple 0 Dst" instruction for some unfathomable reason, we should still be because the run-time system will now refuse to load a module containing such an instruction.
2010-05-20erts: Stop supporting non-literal empty tuplesBjörn Gustavsson
Since R12B, empty tuples are literals. Thus the compiler will no longer generate the instruction: put_tuple 0 Destination for creating an empty tuple. It is now time to stop supporting that instruction in the run-time system. While we are at it, correct a typo.
2010-05-20compile: Remove code that is only executed on SolarisBjörn Gustavsson
On Solaris only, the 'time' option would include the process size for the Erlang virtual machine in its output. Since few compiler developers use Solaris nowadays, remove the code.
2010-05-20Do not cover-analyze core_scanBjörn Gustavsson
Compiling from *.core files is not a supported feature, and writing test cases to improve the coverage of core_scan will not help us to find more bugs in the compiler.
2010-05-20core_SUITE_data: Don't ignore *.core files in this directoryBjörn Gustavsson

2010-05-15fix livelock in erts_poll_info_kp()Mikael Pettersson
erts_poll_info_kp() [defined in erts/emulator/sys/common/erl_poll.c via some name-mangling trickery] contains a code path that can end up in an infinite loop, causing a livelock. There is a block of code inside #if ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE that is supposed to iterate over a linked list of ErtsPollSetUpdateRequestsBlocks and update two variables based on the sizes of these blocks. The bug is that the loop forgets to advance the list pointer to the next element, so if the loop is entered at all (the initial list pointer is non-NULL), the thread falls into an infinite loop. This patch, against R13B03 but applies fine to today's git, fixes the bug by adding a statement to advance the list pointer in the loop. All other loops over this list appear to be correct. Thanks to Chetan Ahuja for the original report of a livelock problem in erts_poll_info_kp().

2010-05-12Remove opaque declarations from the attributesBjörn Gustavsson
-opaque declarations should not be retained in the attributes (because they will be loaded along with the code and are not useful). While at it, filter away those Dialyzer attributes as early as possible - in v3_kernel.
