Reject loading modules with slash in name
2018-02-20Fix regression introduced in d468fcbb / OTP-14816John Högberg
The ~p format specifier made file:consult/1 hysterically slow on one of our test machines that had a unicode character in the root of the code path; all paths were printed as lists and indented with way too much whitespace. Using ~w avoids this issue by never indenting.

2018-02-14beam_block: Combine blocks when running beam_block the second timeBjörn Gustavsson
1a029efd1ad47f started to run the beam_block pass a second time, but it did not attempt to combine adjacent blocks. Combining adjacent blocks leads to many more opportunities for optimizations. After doing some diffing in generated code, it turns out that there is no benefit for beam_split to split out line instructions from blocks. It seems that the only reason it was done was to slightly simplify the implementation of the no_line_info option in beam_clean.
2018-02-14Disable CSE for floating point operationsBjörn Gustavsson
As a preparation for combining blocks before running beam_block for the second time, disable CSE for floating point operations because it will generate invalid code.

2018-02-12Automatically start lcnt server on first useJohn Högberg
lcnt:collect is documented as implicitly starting the lcnt server but didn't do so prior to this commit. I've decided to extend this behavior to all operations as the overhead is negligible and it's a bit more convenient to use.
2018-02-12Fix unsafe use of 'allocate' where 'allocate_zero' should be usedBjörn Gustavsson
The more aggressive optimizations of 'allocate_zero' introduced in cb6fc15c35c7e could produce unsafe code such as the following: {allocate,0,1}. {bif,element,{f,0},[{integer,1},{x,0}],{x,0}}. The code is not safe because if element/2 fails, the runtime system may scan the stack and find garbage that looks like a catch tag, and would most probably crash. Fix the problem by making beam_utils:is_killed/3 be more conservative when asked whether a Y register will be killed. Also fix an unsafe move upwards of an allocation instruction in beam_block.
