2015-01-26hipe: remove HIPE_ALLOC_CODE macroMikael Pettersson
The HIPE_ALLOC_CODE macro in the HiPE runtime was introduced ages ago to allow x86 and amd64 to switch from erts_alloc() to an mmap() implementation with proper flag setting. Nowadays the macro is identical on all platforms, and serves no purpose. Delete the macro, move the hipe_alloc_code() prototype to hipe_arch.h, and simplify hipe_bifs_enter_code_2().

2015-01-11hipe: fix ARM/Thumb interworkingMikael Pettersson
HiPE on ARM is currently severely broken if the rest of the VM is compiled to run in Thumb mode -- calling native code quickly ends up executing code in the wrong mode and crashing the VM. This is a problem on e.g. Ubuntu which configures its system GCC to generate Thumb by default. It can also be triggered by overriding CC or CFLAGS when compiling the VM. There were three issues that caused the breakage: 1. Assembly-coded functions in hipe_arm_glue.S weren't explicitly tagged as functions, preventing the linker from generating the correct mode-switching call instructions for calls from C to these functions. Fixed by tagging those symbols as functions. 2. A few BIF wrappers were so simple that they performed tailcalls to the C BIFs. This fails to switch mode when C is in Thumb. Fixed by performing ordinary recursive calls when C is in Thumb. 3. The assembly-coded source files weren't explicitly tagged as ARM. Tested with the HiPE testsuite on ARMv7, with the VM built as ARM and as Thumb. Also manually inspected the object code for the beam executable and checked that call sites from C to HiPE's ARM runtime code and vice versa used the correct mode-switching instructions.

This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)

Also removed old legacy fallback that is no longer used
2014-12-19erts: Introduce thread suspend functionsLukas Larsson
These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

Turns out that isfinite emits a function call and not an instruction in gcc, this makes estone float arith about 50-75% slower. finite emits the instruction so we use that instead.
