* maint: Bump version of crash dumps to 0.4 Verify that binaries of different sizes are dumped correctly Don't dump literal areas that are not referenced at all Dump literals separately to avoid incomplete heap data Implement dumping of maps in crash dumps Buffer writing of crash dumps Conflicts: erts/emulator/beam/erl_alloc.types
2017-10-18Buffer writing of crash dumpsBjörn Gustavsson
Writing of crash dumps were done using unbuffered IO. This is slow since many small writes are done. Use a FILE* with an allocated buffer to obtain buffered IO. I wrote a small test program that created 50000 binaries of 200 bytes each and then created a crash dump. The crash dumping was an order of magnitude faster with buffered IO than without.

2017-07-17erts: Remove ERTS_SMP and USE_THREAD definesLukas Larsson
This refactor was done using the unifdef tool like this: for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done where defile contained: #define ERTS_SMP 1 #define USE_THREADS 1 #define DDLL_SMP 1 #define ERTS_HAVE_SMP_EMU 1 #define SMP 1 #define ERL_BITS_REENTRANT 1 #define ERTS_USE_ASYNC_READY_Q 1 #define FDBLOCK 1 #undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT #define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0 #define ERTS_POLL_USE_WAKEUP_PIPE 1 #define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1 #undef ERTS_HAVE_PLAIN_EMU #undef ERTS_SIGNAL_STATE

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.
2014-11-04erts: Make erts_printf work with non-blockingLukas Larsson
Now that stdout can be set as non-blocking by the ttsl driver we can no longer use putc and friends for the stdout/stderr streams. Therefore we fallback on write. OTP-12239
