Provides stack-cleaning compilers for x86_64:
* as
* cc
* c++
* fortran
Each of them modify the generated/given X86_64 assembly by prepending stack-cleanup code to each function:
movq $0x7ffff7ff8000, %r11
cmpq %r11, %rsp
jbe .Lstack_cleaner_done0
movq $QSIZE, %r11
.Lstack_cleaner_loop0:
movq $0, OFFSET(%rsp,%r11,8)
subq $1, %r11
jne .Lstack_cleaner_loop0:
.Lstack_cleaner_done0:
The modification of the assembly is done by the clean-stack-filter program.
If the underlying compiler is clang, it might be necessary to add the -no-integrated-as flag in order to force the
usage of an external assembler.
