2015-01-09Improve optimization of bs_start_match2Björn Gustavsson
2015-01-09Extend count_bits_matched/3 to handle the UTF instructionsBjörn Gustavsson
While we are, clean up the comments and rearrange the code for clarity. Also add a test to cover the last uncovered line in beam_dead.erl.
2015-01-09misc_SUITE: Cover the exception handling code in beam_deadBjörn Gustavsson
Amend the test suite to call beam_dead as originally intended (and not beam_block), and modify the input data so that the exception will occur within the try ... catch block in function/2.
2015-01-09Generalize optimizations using shortcut_rel_op/4Björn Gustavsson
Better optimizations with less code.
2015-01-09beam_dead: Optimize branches from relational conditionalsBjörn Gustavsson
The BEAM compiler translates code such as: is_hex_digit(D) when $0 =< D, D =< $9 -> true; is_hex_digit(D) when $a =< D, D =< $z -> true; is_hex_digit(D) when $A =< D, D =< $Z -> true; is_hex_digit(_) -> false. to something like this: L0: test is_ge L1 {x,0} 48 test is_ge L1 57 {x,0} move true {x,0} return. L1: test is_ge L2 {x,0} 97 test is_ge L2 122 {x,0} move true {x,0} return L2: test is_ge L3 {x,0} 65 test is_ge L3 90 {x,0} move true {x,0} return L3: move false {x,0} return We can see that tests will be repeated even if they cannot possibly succeed. For instance, if we pass in {x,0} equal to 32, the first test that {x,0} is greater than or equal to 48 at L0 will fail. The control will transfer to L1, where it will be tested whether {x,0} is greater than 97. That test will fail and control will pass to L2, where again the test will fail. The compiler can do better by short-circuiting repeating tests: L0: test is_ge L3 {x,0} 48 test is_ge L1 57 {x,0} move true {x,0} return. L1: test is_ge L2 {x,0} 97 test is_ge L3 122 {x,0} move true {x,0} return L2: test is_ge L3 {x,0} 65 test is_ge L3 90 {x,0} move true {x,0} return L3: move false {x,0} return

2014-12-19erts: Make main thread safe from pipe closed eventLukas Larsson
2014-12-19erts: Improve crash dumpsLukas Larsson
This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)
2014-12-19erts: Rename sys_sigset to sys_signalLukas Larsson
Also removed old legacy fallback that is no longer used
2014-12-19erts: Introduce thread suspend functionsLukas Larsson
These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

2014-12-15erts: Fix big-endian issue with printf_putcLukas Larsson
On little-endian machines, doing &int will give the smallest byte which is what we want to give to write. But on big-endian it will give the highest byte, which will always be \000 here which results in write never doing any writes. So we have to cast c to an unsigned char before passing it to write.
