Ulrich Weigand 1ef2cec146 Fix ppcf128 component access on little-endian systems ... The PowerPC 128-bit long double data type (ppcf128 in LLVM) is in fact a pair of two doubles, where one is considered the "high" or more-significant part, and the other is considered the "low" or less-significant part. When a ppcf128 value is stored in memory or a register pair, the high part always comes first, i.e. at the lower memory address or in the lower-numbered register, and the low part always comes second. This is true both on big-endian and little-endian PowerPC systems. (Similar to how with a complex number, the real part always comes first and the imaginary part second, no matter the byte order of the system.) This was implemented incorrectly for little-endian systems in LLVM. This commit fixes three related issues: - When printing an immediate ppcf128 constant to assembler output in emitGlobalConstantFP, emit the high part first on both big- and little-endian systems. - When lowering a ppcf128 type to a pair of f64 types in SelectionDAG (which is used e.g. when generating code to load an argument into a register pair), use correct low/high part ordering on little-endian systems. - In a related issue, because lowering ppcf128 into a pair of f64 must operate differently from lowering an int128 into a pair of i64, bitcasts between ppcf128 and int128 must not be optimized away by the DAG combiner on little-endian systems, but must effect a word-swap.
