From: Michael Meissner <meissner@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/meissner/heads/work077)] Use correct names for __ibm128 if long double is IEEE 128-bit. Date: Thu, 27 Jan 2022 18:35:30 +0000 (GMT) [thread overview] Message-ID: <20220127183530.A2F8E3850428@sourceware.org> (raw) https://gcc.gnu.org/g:f7e25436afcb4233dda8c439698d57ed78975869 commit f7e25436afcb4233dda8c439698d57ed78975869 Author: Michael Meissner <meissner@linux.ibm.com> Date: Thu Jan 27 13:35:12 2022 -0500 Use correct names for __ibm128 if long double is IEEE 128-bit. If you are on a PowerPC system where the default long double is IEEE 128-bit, GCC will use the wrong names for some of the conversion functions for the __ibm128 type. What is happening is when the defult long double is IEEE 128-bit, the various convert, truncation, and extend functions did not specify a default name for the conversion. The machine indepentent portions of the compiler would construct a call with an 'if' name (IFmode being the mode for IBM 128-bit floating point). This patch specifies to use the tradiation 'tf' name for these conversion functions. 2022-01-27 Michael Meissner <meissner@the-meissners.org> gcc/ PR target/104253 * config/rs6000/rs6000.cc (TARGET_IEEEQUAD_DEFAULT): If the compiler used to build the current compiler defaults to IEEE 128-bit long double, make that the default for this build.
