these were using were different, but with equivalent definitions.
With `ldc -O3`, the following functions now all compile to the exact same code:
{{{
int[int] y;
void foo(int x) {
if (x in y) {
auto z = x in y;
sink(*z);
}
}
void bar(int x) {
if (x in y) {
sink(y[x]);
}
}
void baz(int x) {
if (auto p = x in y) {
sink(*p);
}
}
}}}
commandline system: `-output-(bc|ll|s)` used to disable generation of an object
file unless explicitly requested with `-output-o`. Now they do so again.
are available for extern(C) functions on x86-64.
Interestingly, llvm-g++ seems to have a very similar bug: http://llvm.org/pr4242
(So this breaks ABI-compatibility with llvm-gcc for this corner case, but gains
it with gcc...)
To clarify, this is about code like this:
{{{
struct S { void*[3] data; }
struct T { void*[2] data; }
// The T should be passed in memory, and p in the last int register.
extern(C) S fail(int, int, int, int, T t, void* p) {
S s;
s.data[0] = t.data[0];
s.data[1] = t.data[1];
s.data[2] = p;
return s;
}
}}}
which should generate code functionally equivalent to this:
{{{
extern(C) S* succeed(S* s, int, int, int, int, T t, void* p) {
s.data[0] = t.data[0];
s.data[1] = t.data[1];
s.data[2] = p;
return s;
}
}}}
(with the same definitions for S and T)
or because it's a static array) by giving it the pointer type instead of the
type itself.
This fixes Derelict compilation on x86-64, where the ABI wasn't expecting a
static array to be passed in at all.
even blink at them they seem to break due to being linkonce (if compiled with
any optimization level > 0), so let's give them weak linkage instead.
The difference is that unreferenced linkonce symbols can be deleted, while
weak symbols need to be preserved.
function definition issue. Please test!
Also change linkage of __interfaceInfos to external (same as __Class, __vtbl,
__init). The other change might make this superfluous.
called on an `AliasDeclaration`; just printing the name will do. This fixes
#305, which otherwise tries to generate
{{{
class E {
void A() {
alias /* recurse into E->toCBuffer() */ m;
}
}
}}}
by way of an infinite recursion (causing a segfault when the stack runs out).
