Bug ID: 37607
Summary: LLD does not create segments for output sections
coming after .ARM.attributes in linkerscript
Product: lld
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: konstantin.schw...@hightec-rt.com
CC: llvm-bugs@lists.llvm.org
LLD does not create segments for output sections coming after .ARM.attributes
section patterns in linkerscripts.
Consider the following assembler file and linker script:
// test.s
.global _start
_start:
nop
// linker.script
ENTRY(_start)
SECTIONS {
.ARM.attributes : { *(.ARM.attributes) }
.text : {
*(.text*)
}
}
llvm-readelf gives the following output:

Reordering the output section description into
// linker2.script
ENTRY(_start)
SECTIONS {
.text : {
*(.text*)
}
.ARM.attributes : { *(.ARM.attributes) }
}
gives the expected result:

arm-none-eabi-ld.bfd produces the expected output with both linkerscripts.
