Bug ID: 23020
Summary: MC misassembles data in .eh_frame with big endian
aarch64
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: MC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
given
-----------------------------
.section .eh_frame
d:
.section foo
.long d - e + 4
.section .eh_frame
e:
--------------------------------
"llvm-mc -triple=aarch64_be-linux-gnu" produces a foo section with
Hex dump of section 'foo':
0x00000000 00000004
but gas compiled for the same triple produces
Hex dump of section 'foo':
0x00000000 04000000
The error is that we flip any fixup that touches the .eh_frame section. The
code handling the .cfi_* directives should instead be marking which fixup need
this.
