LLVM backend for 6502
a867f37897
For function calls on the 64-bit PowerPC SVR4 target, each parameter is mapped to as many doublewords in the parameter save area as necessary to hold the parameter. The first 13 non-varargs floating-point values are passed in registers; any additional floating-point parameters are passed in the parameter save area. A single-precision floating-point parameter (32 bits) must be mapped to the second (rightmost, low-order) word of its assigned doubleword slot. Currently LLVM violates this ABI requirement by mapping such a parameter to the first (leftmost, high-order) word of its assigned doubleword slot. This is internally self-consistent but will not interoperate correctly with libraries compiled with an ABI-compliant compiler. This patch corrects the problem by adjusting the parameter addressing on both sides of the calling convention. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165714 91177308-0d34-0410-b5e6-96231b3b80d8 |
