2012-07-20Revise the autoconf tests for double middle endianness.Mike Sperber
The previous iteration didn't work for big-endian systems. Now use code very close to what Erts does internally. Also, only warn when the double endianness is unknown - i.e. when we're cross-compiling.
2012-07-17Add test for floating-point output to float_SUITE.Mike Sperber
This catches endianness problems, such as recently reported for ARMs.
2012-03-23Unbreak floating point on middle-endian machines.Mike Sperber
On some ARMs (and maybe other platforms), doubles are stored with the the two 32-bit words reversed with respect to more common architectures. The symptom is this: > io_lib:write(1.0). "0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000005299808824" Detect that and account for it when decoding floats.

2012-02-21erts: Fail binary_to_term if bignum arity is too largeSverker Eriksson
2012-02-21erts: Fix bignum-bug in ETS with compressed optionSverker Eriksson
A large 64-bit immediate number will be stored as SMALL_BIG_EXT by ETS compressed format. When uncompressing, the SMALL_BIG_EXT was first decoded as as bignum (by bytes_to_big) and then turned into a small (by big_norm). This works for normal "binary_to_term" as decoded_size() over-estimates the needed heap size. But for ETS no over-estimation is done as the real term size is known and stored in DbTerm. Fixed by preventing bytes_to_big() from writing bignum digit when the number is seen to fit in an immediate.

2012-01-31erts: Correct incorrect assertion in erl_alloc_util.cBjörn Gustavsson
The incorrect assertion would fire when '+Muramv true' has been given, i.e. when a reallocation always forces a move. Change the assertion to not call the lock checker if the mutex is not used (because the allocator will only be accessed from a specific scheduler and thus no lock is needed).
