From 37bb78cb8c1fb6b5813407c8856b1557359e6343 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 19 Oct 2017 17:32:20 +0000 Subject: Install correct bits/long-double.h for MIPS64 (bug 22322). Similar to bug 21987 for SPARC, MIPS64 wrongly installs the ldbl-128 version of bits/long-double.h, meaning incorrect results when using headers installed from a 64-bit installation for a 32-bit build. (I haven't actually seen this cause build failures before its interaction with bits/floatn.h did so - installed headers wrongly expecting _Float128 to be available in a 32-bit configuration.) This patch fixes the bug by moving the MIPS header to sysdeps/mips/ieee754, which comes before sysdeps/ieee754/ldbl-128 in the sysdeps directory ordering. (bits/floatn.h will need a similar fix - duplicating the ldbl-128 version for MIPS will suffice - for headers from a 32-bit installation to be correct for 64-bit builds.) Tested with build-many-glibcs.py (compilers build for mips64-linux-gnu, where there was previously a libstdc++ build failure as at ).
