Subject: [PATCH] x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
|
||||
|
||||
When -z separate-code, which is enabled by default for Linux/x86, is
|
||||
used to create executable, ld won't place any data in the code-only
|
||||
PT_LOAD segment. If there are no data sections placed before the
|
||||
code-only PT_LOAD segment, the program headers won't be mapped into
|
||||
any PT_LOAD segment. When the executable tries to access it (based
|
||||
on the program header address passed in AT_PHDR), it will lead to
|
||||
segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
|
||||
there may be no data sections before the text section so that the
|
||||
first PT_LOAD segment won't be code-only and will contain the program
|
||||
header.
|
||||
|
||||
Testcases are adjusted to either pass "-z noseparate-code" to ld or
|
||||
discard the .note.gnu.property section. A Linux/x86 run-time test is
|
||||
added.

Subject: [PATCH] x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=utf8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
|
||||
If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
|
||||
corresponding x86 instruction set isnât used. When merging properties
|
||||
from 2 input files and one input file doesn't have the
|
||||
GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
|
||||
it neither. This patch removes the GNU_PROPERTY_X86_ISA_1_USED
|
||||
property if an input file doesn't have it.
|
||||
|
||||
This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
|
||||
GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
|
||||
requirement.

Subject: [PATCH] x86: Properly add X86_ISA_1_NEEDED property
|
||||
|
||||
Existing properties may be removed during property merging. We avoid
|
||||
adding X86_ISA_1_NEEDED property only if existing properties won't be
|
||||
removed.

|
||||
* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Don't
|
||||
add X86_ISA_1_NEEDED property only if existing properties won't
|
||||
be removed.
