From 641b407763ecfee5d4ac86d8ffe9eb1eeea5fd10 Mon Sep 17 00:00:00 2001 From: Michael Meissner Date: Sat, 5 Mar 2022 20:11:38 -0500 Subject: [PATCH] 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. 2022-03-05 Michael Meissner gcc/ PR target/99708 * config/rs6000/rs6000-c.c (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. Backport change to master branch on 2022-02-17. gcc/testsuite/ PR target/99708 * gcc.target/powerpc/pr99708.c: New test.
