Add method to query segments for specified output section name. Return error if the section is assigned to unknown segment. Check matching of sections to segments during layout on the subject of correctness. NOTE: no actual functionality of using custom segments is implemented.

This group of tests checks usage of default headers during linking,
|
|
when PHDRS command is not defined or defined empty in linker scripts.
|
|
|
|
This test uses a single X86-64 input object, simple.o, created with the
|
|
following X86-64 assembly code:
|
|
|
|
*** simple.S:
|
|
|
|
(command line clang -c simple.S -o simple.o)
|
|
|
|
.text
|
|
main:
|
|
mov $1, %eax
|
|
movq $1, %rdi
|
|
movq $msg, %rsi
|
|
movq $14, %rdx
|
|
syscall
|
|
ret
|
|
|
|
.globl _start
|
|
_start:
|
|
call main
|
|
mov $60, %eax
|
|
syscall
|
|
ret
|
|
