Bug ID: 21505
Summary: objcopy fails --prefix-symbols on armv7
Product: binutils
Version: 2.28
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: cocoarui09 at gmail dot com
Target Milestone: ---
Hi there,
I've installed binutils 2.28 via homebrew on Mac os sierra 10.12.4, and
changed gobjdump name to objdump, also the objcopy.
I've checked the .o file by: `lipo -info hmac_md5.o`,
and it print out:
`Non-fat file: hmac_md5.o is architecture: armv7`.
then I tried to change symbol prefix name by:
`objcopy --prefix-symbols=hc_ hmac_md5.o`
and it print out:
`gobjcopy: hmac_md5.o: file format error`
and when I typed in console:
`objdump -t hmac_md5.o`
it print out:
`hmac_md5.o： file format mach-o-arm`
BTW, I also tried the arm64 hmac_md5.o, it workd well. Please help.
