From f29b7c492d8a06581cf1b573b7e5907daa8c139c Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Fri, 20 Apr 2018 18:06:44 +0100 Subject: [PATCH] Remove the error handling wrapper from log Introduce new log symbol version that doesn't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The wrapper is disabled for sysdeps/ieee754/dbl-64 by using empty w_log.c and enabled for targets with their own log implementation by including math/w_log.c. The compatibility symbol version still uses the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously logl was an alias of log, now it points to the compatibility symbol with the wrapper, because it still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g. arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The __log_finite symbol is now an alias of log. Both __log_finite and log set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include was added before macro definitions that may affect that header. Tested with build-many-glibcs.py. * math/Versions (GLIBC_2.29): Add log. * math/w_log_compat.c (__log_compat): Change to versioned compat symbol. * math/w_log.c: New file. * sysdeps/i386/fpu/w_log.c:
