12 years agoOn PowerPC64, integer return values (as well as arguments) are supposed
Ulrich Weigand [Mon, 5 Nov 2012 19:39:45 +0000 (19:39 +0000)]
On PowerPC64, integer return values (as well as arguments) are supposed
to be extended to a full register.   This is modeled in the IR by marking
the return value (or argument) with a signext or zeroext attribute.

However, while these attributes are respected for function arguments,
they are currently ignored for function return values by the PowerPC
back-end.  This patch updates PPCCallingConv.td to ask for the promotion
to i64, and fixes LowerReturn and LowerCallResult to implement it.

The new test case verifies that both arguments and return values are
properly extended when passing them; and also that the optimizers
understand incoming argument and return values are in fact guaranteed
by the ABI to be extended.

The patch caused a spurious breakage in CodeGen/PowerPC/coalesce-ext.ll,
since the test case used a "ret" instruction to create a use of an i32
value at the end of the function (to set up data flow as required for
what the test is intended to test).  Since there's now an implicit
promotion to i64, that data flow no longer works as expected.  To fix
this, this patch now adds an extra "add" to ensure we have an appropriate
use of the i32 value.

Ulrich Weigand [Mon, 5 Nov 2012 19:13:42 +0000 (19:13 +0000)]
On PowerPC64, integer arguments and return values need to be sign- or
zero-extended to 64 bits.  This information is currently provided to
the back end by setting "signext" or "zeroext" attributes.  However,
this is done only for integer types *smaller* than i32, not for i32
itself.  This causes clang to generate code violating the ABI, which
results in a failure of the tramp3d-v4 test case (due to calling a
system library routine without ABI-required extension).

This patch implements custom versions of classifyArgumentType and
classifyReturnType for PPC64_SVR4_ABIInfo, which are the same as the
default versions except that they also classify "int" and "unsigned int"
as types needing extending.  This fixed tramp3d-v4 on PowerPC64.
