[ELF] Define __ehdr_start symbol This symbol can be used by the program to examine its own headers. Differential Revision: https://reviews.llvm.org/D23750 llvm-svn: 279452
2016-08-23 02:44:04 +08:00
# REQUIRES: x86
# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %s -o %t.o
# RUN: echo "SECTIONS { }" > %t.script
[ELF] Define __ehdr_start unconditionally even when using linker script This behavior differs from the semantics implemented by GNU linkers which only define this symbol iff ELF headers are in the memory mapped segment. Differential Revision: https://reviews.llvm.org/D33019 llvm-svn: 302687

# RUN: ld.lld %t.o -script %t.script -o %t
[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651
