2018-07-10erts: Fix buggy calls to erts_sys_explicit_8bit_getenvSverker Eriksson
Two of them only affect valgrind builds and the one for ERL_CRASH_DUMP_NICE seems benign. Return value changed in c2d70945dce9cb09d5d7120d6e9ddf7faac8d230 old -> new -1 -> 0 not found 0 -> 1 found ok 1 -> -1 found but too big

2018-06-28Fix a race condition when generating async operation idsJohn Högberg
The counter used for generating async operation ids was a plain int shared between all ports, which was incorrect but mostly worked fine since the ids only had to be unique on a per-port basis. However, some compilers (notably GCC 8.1.1) generated code that assumed that this value didn't change between reads. Using a shortened version of enq_async_w_tmo as an example: int id = async_ref++; op->id = id; //A return id; //B In GCC 7 and earlier, `async_ref` would be read once and assigned to `id` before being incremented, which kept the values at A and B consistent. In GCC 8, `async_ref` was read when assigned at A and read again at B, and then incremented, which made them inconsistent if we raced with another port. This commit fixes the issue by removing `async_ref` altogether and replacing it with a per-port counter which makes it impossible to race with someone else.
2018-06-27Fix internal compiler error for map_get/2Björn Gustavsson
Code such as that the following: Val = map_get(a, Map), Map#{a:=z} %Could be any map update would incorrectly cause an internal consistency check failure: Internal consistency check failed - please report this bug. Instruction: {put_map_exact,{f,0},{x,0},{x,0},1,{list,[{atom,a},{atom,z}]}} Error: {bad_type,{needed,map},{actual,term}}: Update beam_validator so that it understands that the second argument for map_get/2 is a map.
2018-06-27beam_type: Fix unsafe optimizationBjörn Gustavsson
beam_type assumed that the operand for the bs_context_to_binary instruction must be a binary. That is not correct; bs_context_to_binary accepts anything. Based on the incorrect assumption, beam_type would remove other test instructions. The bug was introduced in eee8655788d2, which was supposed to be just a refactoring commit. https://bugs.erlang.org/browse/ERL-655
