[erlang-questions] diffrent emulator modes

[Sanjaya Vitharana]

Hi All,

1.) What is the diffrence between below each and every erlang emulator modes (found in erl_bif_info.c)? are there any docs discribing those?

" [source]"
" [64-bit]"
" [smp:%bpu]"
" [async-threads:%d]"
" [hipe]"
" [kernel-poll:%s]"
" [no-frag]"
" [io-thread]"
" [io-at-once]"
" [port-tasks]"
" [hybrid heap]"
" [incremental GC]"
" [type-assertions]"
" [debug-compiled]"
" [lock-checking]"
" [purify-compiled]"
" [valgrind-compiled]"


2.) How to configure & make erlang emulator in diffrent modes (above)

I am specially interested on below areas for debugging purposes (erlang port driver debugging)

type-assertions
debug compiled emulator
Runing debug compiled emulator in gdb
emulator compiled for valgrind

 
3.) how to run erlang in those modes ?


Thanks in advance,

Sanjaya Vitharana
