A testcase
When a padding in file is used to align PT_GNU_RELRO segment, the maximum
padding size is maximum page size minus 1, which may lead to large file
size:
[hjl@gnu-tools-1 relro]$ make
as -o x.o x.s
./ld -z relro -T ld.t -z max-page-size=0x200000 -z common-page-size=0x1000
-shared -o x.so x.o
ls -l x.so
-rwxrwxr-x 1 hjl hjl 2419808 Mar 28 20:17 x.so
[hjl@gnu-tools-1 relro]$
