From: Michael Meissner <meissner@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/meissner/heads/work078)] Define __SIZEOF_FLOAT128__ and __SIZEOF_IBM128__. Date: Thu, 17 Feb 2022 00:37:59 +0000 (GMT) [thread overview] Message-ID: <20220217003759.369343858027@sourceware.org> (raw) https://gcc.gnu.org/g:8dce1b423d3705fd8ba7923f5ffbd0cc8af89239 commit 8dce1b423d3705fd8ba7923f5ffbd0cc8af89239 Author: Michael Meissner <meissner@linux.ibm.com> Date: Wed Feb 16 19:36:17 2022 -0500 Define __SIZEOF_FLOAT128__ and __SIZEOF_IBM128__. Define the sizes of the PowerPC specific types __float128 and __ibm128 if those types are enabled. This patch will define __SIZEOF_IBM128__ and __SIZEOF_FLOAT128__ if their respective types are created in the compiler. Currently, this means both of these will be defined if float128 support is enabled. But at some point in the future, __ibm128 could be enabled without enabling float128 support and __SIZEOF_IBM128__ would be defined. 2022-02-16 Michael Meissner <meissner@the-meissners.org> gcc/ PR target/99708 * config/rs6000/rs6000-c.cc (rs6000_cpu_cpp_builtins): Define __SIZEOF_IBM128__ if the IBM 128-bit long double type is created. Define __SIZEOF_FLOAT128__ if the IEEE 128-bit floating point type is created. gcc/testsuite/ PR target/99708 * gcc.target/powerpc/pr99708.c: New test.
