File fix-922619.patch of Package mame
Description: Fix FTBFS on power "not a constant expression" There are some explanation upstream : https://github.com/mamedev/mame/issues/3157 and this probably due to the fact that IBM 128bit long double format is not constant folded. I slighlty rewrote ""_kHz_XTAL(long double clock) and ""_MHz_XTAL(long double clock) the way ""_kHz_XTAL(unsigned long long clock) and ""_MHz_XTAL(unsigned long long clock) which makes the compiler happy. Also including an upstream change about rounding to get same results as on x86 : https://github.com/mamedev/mame/pull/5164 Author: Frédéric Bonnard <frediz@debian.org> --- This patch header follows DEP-3: http://dep.debian.net/deps/dep3/ As per comments in above issue#3157, this patch not accepted upstream, but allow ppc64le to build. --- a/src/emu/xtal.h +++ b/src/emu/xtal.h @@ -81,8 +81,8 @@ constexpr XTAL operator *(double mult, const XTAL &xtal) { return XTAL(xtal.base(), mult * xtal.dvalue()); } constexpr XTAL operator ""_Hz_XTAL(long double clock) { return XTAL(double(clock)); } -constexpr XTAL operator ""_kHz_XTAL(long double clock) { return XTAL(double(clock * 1e3)); } -constexpr XTAL operator ""_MHz_XTAL(long double clock) { return XTAL(double(clock * 1e6)); } +constexpr XTAL operator ""_kHz_XTAL(long double clock) { return XTAL(double(clock) * 1e3); } +constexpr XTAL operator ""_MHz_XTAL(long double clock) { return XTAL(double(clock) * 1e6); } constexpr XTAL operator ""_Hz_XTAL(unsigned long long clock) { return XTAL(double(clock)); } constexpr XTAL operator ""_kHz_XTAL(unsigned long long clock) { return XTAL(double(clock) * 1e3); }
