[Qemu-devel] [PATCH v4 2/5] softfloat: Resolve type mismatches between declaration and implementation |
Date: |
Tue, 4 Jan 2011 20:39:08 +0100 |
The original SoftFloat 2.0b library avoided the use of custom integer types
in its public headers. This requires the definitions of int{8,16,32,64} to
match the assumptions in the declarations. This breaks on BeOS R5 and Haiku/x86,
where int32 is defined in {be,os}/support/SupportDefs.h in terms of a long
rather than an int. Spotted by Michael Lotz.
Since QEMU already breaks this distinction by defining those types just above,
do use them for consistency and to allow #ifndef'ing them out as done for
[u]int16 on AIX.
Note that the BeOS/Haiku types are exact-width types though.
v3:
* Split off as intermediate step.
v2:
* Rebased.
