Bug ID: 41356
Summary: LLD does not handle " " in InputSectionDescriptions
correctly
Product: lld
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: peter.sm...@linaro.org
CC: llvm-bugs@lists.llvm.org, peter.sm...@linaro.org
According to the ld manual, strings containing separation characters can be
double quoted. The intention is that the double quotes are not part of the
string.
https://sourceware.org/binutils/docs/ld/Script-Format.html#Script-Format
Strings such as file or format names can normally be entered directly. If the
file name contains a character such as a comma which would otherwise serve to
separate file names, you may put the file name in double quotes. There is no
way to use a double quote character in a file name.
LLD isn't getting this right, it is treating the " as a required character in
the string.
cat match.s
.section "my name with quotes", "aw", %progbits
lab: .word 10
cat match.lds
SECTIONS {
.data : { *("my name with quotes") }
}
ld.bfd match.o -T match.lds --print-map
.data 0x0000000000000000 0x2
*(my name with quotes)
my name with quotes
0x0000000000000000 0x2 match.o
ld.lld match.o -T match.lds --print-map
0 0 0 1 .data
0 0 0 1 match.o:(.data)
0 0 2 1 my name with quotes
0 0 2 1 match.o:(my name with
quotes)
Note that lld has not matched the section my name with quotes to *("my name
with quotes")
If I change .section "\"my name with quotes\"", "aw", %progbits then the
results change so that ld.bfd does not match *("my name with quotes") but LLD
does.
ld.bfd
my name with quotes"
0x0000000000000000 0x2
"my name with quotes"
0x0000000000000000 0x2 match.o
ld.lld
0 0 0 1 match.o:(.text)
0 0 2 1 .data
0 0 2 1 match.o:("my name with
quotes")
0 0 0 1 lab
2 2 0 1 match.o:(.data)
Found by trying to link the Zephyr RTOS https://www.zephyrproject.org with LLD.
