Bug ID: 98395
Summary: libgcc_s.so.1 almost 10x bigger in gcc-10.2 than
gcc-9.2
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: john.frankish at outlook dot com
Target Milestone: ---
The libgcc_s.so.1 library built with gcc-10.2 is 580kb, whereas the same
library built with gcc-9.2 is 75kb.
Both were built on an x86_64 system with:
CC="gcc -mtune=generic -Os -pipe" CXX="g++ -mtune=generic -Os -pipe"
../configure --prefix=/usr/local --enable-languages=c,c++ --disable-multilib
--disable-bootstrap --with-system-zlib --libexecdir=/usr/local/lib
The almost ten-fold increase in size would seem to indicate something is wrong,
but what?
