Bug ID: 15549
Summary: "b = a + 1" doesn't work right
Product: libraries
Version: trunk
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: MC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
$ cat t.s
a:
.byte 0, 1, 2, 3
b = a + 1
$ clang -c t.s -no-integrated-as
$ readelf -sW t.o
Symbol table '.symtab' contains 6 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000000000000 0 SECTION LOCAL DEFAULT 1
2: 0000000000000000 0 SECTION LOCAL DEFAULT 2
3: 0000000000000000 0 SECTION LOCAL DEFAULT 3
4: 0000000000000000 0 NOTYPE LOCAL DEFAULT 1 a
5: 0000000000000001 0 NOTYPE LOCAL DEFAULT 1 b
$ clang -c t.s
$ readelf -sW t.o
Symbol table '.symtab' contains 6 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000000000000 0 NOTYPE LOCAL DEFAULT 1 a
2: 0000000000000000 0 NOTYPE LOCAL DEFAULT ABS b
3: 0000000000000000 0 SECTION LOCAL DEFAULT 1
4: 0000000000000000 0 SECTION LOCAL DEFAULT 2
5: 0000000000000000 0 SECTION LOCAL DEFAULT 3
With the integrated assembler, b's section index is ABS when it should be a's
section index, and its value is 0 when it should be 1.
