SV: SV: [commited] jit: Support for global rvalue initialization and constructors
Oh ye no it is probably terrible missuse trying to write into the constructor.
=)
Maybe I should look into barring that entrypoint for constructors. Kinda
overlooked
that rvalue arrays could be used as lvalues.

Oh, sorry, I meant when you have an array not in a local variable, and
you try to assign to an index of this array.
Something like:
gcc_jit_rvalue *ctor = gcc_jit_context_new_array_constructor
(ctxt,0,int50arr_type,6,values);
gcc_jit_block_add_assignment (block, 0,
gcc_jit_context_new_array_access(NULL, ctor,
gcc_jit_context_zero(int_type)), some_value);

SV: [commited] jit: Support for global rvalue initialization and constructors
Could you be more specific? I tried the equivalent of:
/*int [50] foobar = {1,2,3,4};
int [50] foo() { int arr[50];
arr = (int [50]){-1,-2,-3,-4,-5,-6};
arr = foobar;
arr = (int [50]){1,2,3,4,5,6};
arr[6] = 1234;
return arr;}
N.B: Not a typo, returning an array.
*/
in test-local-init-rvalue.c with a global and local "arr" and it ran fine. (See
attachment).

Should an assignment to such a value be supported?
