2015-08-31erts,hipe,dialyzer: Fix hipe checkum of target runtime systemSverker Eriksson
Main problem: A faulty HIPE_LITERAL_CRC was not detected by the loader. Strangeness #1: Dialyzer should ask the hipe compiler about the target checksum, not an internal bif. Strangeness #2: The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC checksum. Solution: New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent) HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC. HIPE_LITERALS_CRC represents values that are assumed to stay constant for different VM configurations of the same arch, and are therefor hard coded into the hipe compiler. HIPE_SYSTEM_CRC represents values that may differ between VM variants. By default the hipe compiler asks the running VM for this checksum, in order to create beam files for the same running VM. The hipe compiler can be configured (with "make XCOMP=yes ...") to create beam files for another VM variant, in which case HIPE_SYSTEM_CRC is also hard coded. ToDo: Treat all erts properties the same. Either ask the running VM or hard coded into hipe (if XCOMP=yes). This will simplify and reduce the risk of dangerous mismatches. One concern might be the added overhead from more frequent calls to hipe_bifs:get_rts_param.

2014-03-30Fix frame size adjustment of stack descriptorsYiannis Tsiouris
In case of function calls with arguments that are passed to the stack, the frame size of corresponding stack descriptors needs to be reduced by the number of stack arguments. This commit fixes a bug in this adjustment which was caused by an incorrect check.
2014-03-30Fix counting of arguments of closuresChristos Stavrakakis
Do not rely on MFA name for the arity of functions, since closures have an extra argument. Instead, just use the length of the arguments list.
