[Mingw-w64-public] [PATCH] Add the sincos* functions on arm, calling into sin/cos separately
On arm (unless --enable-experimental=softmath is set), we pass
sin/cos function calls straight through to msvcrt. We normally
provide implementations of the sincos family of functions, that
provide both return values at once. Provide implementations of
these functions that simply call the sin/cos functions.

Re: [Mingw-w64-public] Difference between libpthread.a and libwinpthread.a?
Mike H 2017-07-22 09:23: I downloaded the official installer for Mingw-w64 and then choose posix and x64, and then it doiwnloaed the gcc 7.1.0 toolchain. So I'm sure it's the official files. Exceptions model is 'sjlj' or 'seh'? -- Regards, niXman ___ Dual-target(32 & 64-bit) MinGW-W64 compilers for 32 and 64-bit Windows: https://sf.net/p/mingw-w64/ -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
Re: [Mingw-w64-public] Difference between libpthread.a and libwinpthread.a?
Mike H 2017-07-22 09:23: Hello! Hi, I'm a fan of mingw-w64. But there is one thing I don't understand. What's the difference between libpthread.a and libwinpthread.a? The size of those files are different. Libpthread.a is bigger. I downloaded the official installer for Mingw-w64 and then choose posix and x64, and then it doiwnloaed the gcc 7.1.0 toolchain. So I'm sure it's the official files. I also opened those files with a hex editor, and found that in libthread.a there are several names of c-files, like mutex.c and nanosleep.c. But not in libwinthread.a. Please choose the full path for this files. -- Regards, niXman ___ Dual-target(32 & 64-bit) MinGW-W64 compilers for 32 and 64-bit Windows: https://sf.net/p/mingw-w64/ -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
