The Microblaze build of pixman was failing due to FE_DIVBYZERO not being implemented. It turns out that the usage of it, like fenv.h and feenableexcept() is optional. So the patch simply adds a configure check and disables the appropriate code (which is only use in the tests anyway). This commit also renames the existing patch to follow the patch naming convention, and get a reliable ordering when applying patches.

configure.ac: Verify that the Loongson MMI code can link
|
|
|
|
The Loongson MMI code modifies -march and as a result it breaks linking
|
|
when the rest of the code is built with a different -match/-mtune.
|
|
This patch fixes the problem by trying to link the code instead of just
|
|
compiling it. This patch is already committed upstream.

Subject: Use AC_LINK_IFELSE to check if the Loongson MMI code can link
|
|
|
|
The Loongson code is compiled with -march=loongson2f to enable the MMI
|
|
instructions, but binutils refuses to link object code compiled with
|
|
different -march settings, leading to link failures later in the
|
|
compile. This avoids that problem by checking if we can link code
|
|
compiled for Loongson.
