Switch Cling's execution engine to use LLVM's Orc JIT. The new JIT allows Cling to support:
ARM and PowerPC architectures.
Exceptions. Cling can throw and catch exceptions from interpreted and compiled code.
[cling]$ throw new std::exception();
Exception occurred. Recovering...
Inline assembly. Cling can execute asm statements.
[cling]$ extern "C" int printf(const char*, ...);
[cling]$ int arg1=1, arg2=2, add;
[cling]$ asm ("addl %%ebx, %%eax;" : "=a" (add) : "a" (arg1) , "b" (arg2));
[cling]$ printf( "%d + %d = %d\n", arg1, arg2, add );
1 + 2 = 3
Reduce memory usage caused by excessive memory allocations in Cling lookup routines.
Stabilize error recovery caused by handling of templated declarations.
Implement a user-extendable value streaming engine.
Implement shebang support.
Protect against invalid pointer dereferences.
[cling]$ struct S{ int a; };
[cling]$ ((S*)0x123)->a;
input_line_4:2:2: warning: invalid memory pointer passed to a callee:
((S*)0x123)->a;
^~~~~~~~~~~
[cling]$ ((S*)0)->a;
input_line_5:2:2: warning: null passed to a callee that requires a non-null argument [-Wnonnull]
((S*)0)->a;
^~~~~~~
Redirect stderr and stdout. Cling's users can redirect the output streams.
[cling]$ // Redirects stdout to /tmp/outfile.txt
[cling]$ .> /tmp/outfile.txt
[cling]$ // Toggles back to the prompt
[cling]$ .>
[cling]$ // Redirects stderr to /tmp/errfile.txt
[cling]$ .2> /tmp/errfile.txt
[cling]$ // Redirects stdout and stderr to /tmp/bothfile.txt
[cling]$ .&> /tmp/bothfile.txt
Add #pragma cling directives:
#pragma cling add_include_path("/include/path/")
#pragma cling add_library_path("/library/path/")
#pragma cling load("libUserLib")
Add .@ metacommand to cancel multiline user input.
Add .debug [Constant] metacommand to tune the generated debug information.
