Peter Collingbourne a56d81f4fb llvm-symbolizer: Untag addresses in object files by default.
Any addresses that we pass to llvm-symbolizer are going to be untagged,
while any HWASAN instrumented globals are going to be tagged in the
symbol table. Therefore we need to untag the addresses before using them.

Jordan Rupprecht d884fbde2a [llvm-readelf] Fix core note descriptions
Summary:
Core files have different descriptions for note values. llvm-readelf currently prints the generic note type, which is wrong when using it to read a core file.

To verify the constants/strings, see:
Values: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=include/elf/common.h;h=75c4fb7e9d7c0f780d635ac305f579546b7b071b;hb=HEAD#l571
Strings: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=binutils/readelf.c;h=c31a5c1266b7bb62a485895b01b49e1f832ade35;hb=HEAD#l16881

Note: this does not handle printing the note data for NT_FILE, it just fixes the descriptions.

Hubert Tong 6ca6e91615 [yaml2obj][tests] Fix overly restrictive od output check
Summary:
rL364517 introduced further instances of `od` output checking of the
kind previously corrected by rL363829. This patch corrects the issue by
suppressing output of the input offset. The check remains sufficiently
sensitive to test for the intended value of the specific byte since the
relevant byte value is the only output we are expecting from `od`.

This patch adds a new llvm-mca flag named -print-imm-hex.

By default, the instruction printer prints immediate operands as decimals. Flag
-print-imm-hex enables the instruction printer to print those operands in hex.

This patch also adds support for MASM binary and hex literal numbers (example
0FFh, 101b).

Peter Smith e314a128a9 [AARCH64] Switch relocations R_AARCH64_TLS_TPREL64 and R_AARCH64_DTPMOD64
The ELF for the Arm 64-bit Architecture document originally specified
R_AARCH64_TLS_DTPREL64 = 0x404
R_AARCH64_TLS_DTPMOD64 = 0x405

LLVM correctly followed the document. Unfortunately in binutils these
two codes were reversed:
R_AARCH64_TLS_DTPMOD64 = 0x404
R_AARCH64_TLS_DTPREL64 = 0x405
Given that binaries had shipped this change has become the defacto standard
interpretation of these relocation codes for any toolchain that wanted to
remain compatible with GNU.

To recognize this the latest version of the ABI document has renamed
the relocations to R_AARCH64_TLS_IMPDEF1 and R_AARCH64_TLS_IMPDEF2
permitting a toolchain to choose between the two relocation types, and
recommending that toolchains follow the GNU interpretation for maximum
compatibility.

Given that upstream llvm has never implemented the standard TLS model for
AArch64 so we have no binary legacy, synchronize with GCC so that we don't
create incompatible objects in the future. So far the only visible change
is in llvm-readobj as it can decode these relocations. Tthis change will
mean that llvm-readobj decodes the same way as GNU readelf.

Bob Haarman 6baac18a76 add 'a' to chmod in llvm-lipo executability tests
Summary:
When specifying symbolic permissions with + or -, if none of
a/u/g/o are specified, bits set in the umask are not affected.
This caused the llvm-lipo executability tests to fail on some
systems, e.g. having an umask of 027 would cause chmod -x to not
clear the executable bit for others. This change instead
uses chmod a-x, which clears all the executable bits regardless
of umask.

It removes dtflags.elf-x86-64 binary and elf-dtflags.test.
elf-dtflags.test is excessive because we have the
elf-dynamic-tags.test which test all non-machine specific tags.

It removes testing of --dynamic-table from test\Object\readobj-shared-object.test
(we have the elf-dynamic-tags.test for that), and simplifies this test case.

It moves testing of the headers from readobj-shared-object.test
to elf-file-headers.test.

Adds test/tools/llvm-readobj/elf-file-types.test and test/tools/llvm-readobj/elf-loadname.test.

http://www.sco.com/developers/gabi/latest/ch4.sheader.html)
that section header at index 0 (null section) can have sh_size and
sh_link fields set to non-zero values.

It says (https://docs.oracle.com/cd/E19683-01/817-3677/6mj8mbtc9/index.html):

"If the number of sections is greater than or equal to SHN_LORESERVE (0xff00),
this member has the value zero and the actual number of section header table
entries is contained in the sh_size field of the section header at index 0.
Otherwise, the sh_size member of the initial entry contains 0."

and:

"If the section name string table section index is greater than or equal to SHN_LORESERVE
(0xff00), this member has the value SHN_XINDEX (0xffff) and the actual index of the section
name string table section is contained in the sh_link field of the section header at index 0.
Otherwise, the sh_link member of the initial entry contains 0."

At this moment it is not possible to create custom section headers at index 0 using yaml2obj.

This patch implements this.
