From 5332a3250bd1af88d21b1718d31a5e8e238034c4 Mon Sep 17 00:00:00 2001 From: Hans Wennborg Date: Fri, 1 Feb 2019 11:12:06 +0000 Subject: Merging r352156: ------------------------------------------------------------------------ r352156 | phosek | 2019-01-25 03:42:30 +0100 (Fri, 25 Jan 2019) | 12 lines [AArch64] Make the test for rsr and rsr64 stricter ACLE specifies that return type for rsr and rsr64 is uint32_t and uint64_t respectively. D56852 change the return type of rsr64 from unsigned long to unsigned long long which at least on Linux doesn't match uint64_t, but the test isn't strict enough to detect that because compiler implicitly converts unsigned long long to uint64_t, but it breaks other uses such as printf with PRIx64 type specifier. This change makes the test stricter enforcing that the return type of rsr and rsr64 builtins is what is actually specified in ACLE.
