I suppose so.
Compiling this:
int x __attribute__((__aligned__(32)))
__attribute__((__section__(".data.mostly_readonly")));
generates this:
.file "t.c"
.version "01.01"
gcc2_compiled.:
.globl x
.section .data.mostly_readonly,"aw",@progbits
.align 32
.type x,@object
.size x,4
x:
.zero 4
.ident "GCC: (GNU) 2.96 20000731 (Red Hat Linux 7.3 2.96-113)"
Seems OK?
