If x is subnormal: o For SUSv3-conforming applications compiled with the c99 com- piler driver (see standards(7)), the exponent of x as if x were normalized is returned. o Otherwise, if compiled with the cc compiler driver, -1022, -126, and -16382 are returned for logb(), logbf(), and logbl(), respectively.Studio c99 and gcc control this by linking with the appropriate version of values-xpg[46].o, but clang uses neither of those.The following patch fixes this by following what gcc does, as corrected some time ago in Fix use of Solaris values-Xc.o (PR target/40411) https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02350.html and https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02384.html.Tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu.Differential Revision: https://reviews.llvm.org/D64793llvm-svn: 367866 List of files: /llvm-project-15.0.7/clang/test/Driver/solaris-ld-values.cpp Mon, 05 Aug 2019 14:06:16 +0000 Rainer Orth <ro@gcc.gnu.org>
