Hi. I tried compiling AS on Jetson Tegra K1 which uses ARM processor. I used the gnuc makefile and everything compiles except as_callfunc_arm.cpp.s. It returns error about THUMB instruction not being in IT block. The whole log:

You can also see I tried compiling with -DAS_MAX_PORTABILITY with the idea it will not use the ASM at all, but it still compiled it and threw the error. Is there some kind of flag I need to change? The ASM has defined blocks for THUMB1, THUMB2 and ARM, so techniclly I could disable THUMB and fallback to ARM?

Compiler:

For some reason I cannot post the whole g++ -v here. So I posted it here: http://pastebin.com/n4uXrVXb

Do you also compile with the thumb instructions or the regular arm? My gcc has defined "--with-mode=thumb". When I added the "#ifndef AS_MAX_PORTABILITY" I got it to compile. But when I launch the project it segfaults on AS functions. It manages to create the engine, but the next function which is registering the error callback crashes (quite ironic). At first I thought it was because of asCALL_CDECL, because at that point I was running the AS_MAX_PORTABILITY flag. So I changed it into asCALL_GENERIC and same thing. I posted both of the segfaults. The callstack doesn't go any deeper than this. The whole backtrace only shows the path until it calls this function.

//With CDECL
Program received signal SIGSEGV, Segmentation fault.
0x0002e900 in as::as_engine_create ()
at NodeVision_System/scripting/angelscript_wrapper.cpp:94
94 int r = engine->SetMessageCallback(asFUNCTION(as::MessageCallback), 0, asCALL_CDECL); assert( r >= 0 ); //For errors reports

//With Generic
Program received signal SIGSEGV, Segmentation fault.
0x0002e900 in as::as_engine_create ()
at NodeVision_System/scripting/angelscript_wrapper.cpp:94
94 int r = engine->SetMessageCallback(asFUNCTION(as::MessageCallback), 0, asCALL_GENERIC); assert( r >= 0 ); //For errors reports

Then I tried removing it, just to see if it would go further. But the next function is RegisterStdString, which then calls RegisterStdStringGeneric and crashes.

It also compiled when I removed the AS_MAX_PORTABILITY and instead added the -marm flag (which is the same as --with-mode=arm). In that case everything is the same. It crashes at SetMessageCallback and when I remove it, it calls RegisterStdString, which then calls RegisterStdStringNative and crashes. Here is the full backtrace for both:

Everything works fine on Windows x86 and x64. I'm using the 2.30 version of AS.
