   4 Subject: [PATCH] pixman-private: include <float.h> only in C code
   5
   6 <float.h> is included unconditionally by pixman-private.h, which in
   7 turn gets included by assembler files. Unfortunately, with certain C
   8 libraries (like the musl C library), <float.h> cannot be included in
   9 assembler files:

  11   CCLD     libpixman-arm-simd.la
  12 /home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h: Assembler messages:
  13 /home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h:8: Error: bad instruction `int __flt_rounds(void)'
  14 /home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h: Assembler messages:
  15 /home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h:8: Error: bad instruction `int __flt_rounds(void)'
  16
  17 It turns out however that <float.h> is not needed by assembly files,
  18 so we move its inclusion within the #ifndef __ASSEMBLER__ condition,
  19 which solves the problem.
