the bogus adjustment to 160 from 144 (which is reverted here),
is a single-token commit in upstream r301307, an attempt to
correct a failed build due to an upstream change to compile the
runtime with D_FILE_OFFSET_BITS=64.  The correct fix is here:
just use the right include.  Yes, user-struct-stat64-as-stat is
actually 160 for MIPS o32 and I hear user-struct-stat is also
160 for n32.  There are additional fields appended for
user-struct-stat!  I guess for MIPS it's as bad as it gets for
mixing up kernel and user struct stat.  The context of the patch
doesn't show that in the #else there's the correct include, the
one for <asm/stat.h> to get the kernel-struct-stat.  If you
can't compile it, IMHO the kernel headers are just too old; 3.2
is fine for example.

6 years agoDWARF sort longer dirs before shorter ones in directory table.
Mark Wielaard [Wed, 25 Apr 2018 17:34:00 +0000 (17:34 +0000)]
DWARF sort longer dirs before shorter ones in directory table.

When gcc dwarf2out generates the .debug_line table itself (for example
when generating one for a split DWARF .dwo) it uses natural sorting for
the directory table. Shorter directory paths come before longer directory
paths with the same prefix. This causes the files in the line table to
pick the shorter dir. Creating slightly ineffecient line tables because
the longer directory paths will never be used.

Fix this by changing file_info_cmp () to pick longer directory prefixes
before shorter ones. We still sort files (the compilation unit) without
any directory path before all entries with a directory path, so they
will still use dir entry 0 (the working directory).

A hello.c program would get the following dir and line table before:

Directory table:
 /opt/local/install/gcc/lib/gcc/x86_64-pc-linux-gnu/8.0.1/include
 /usr/include
 /usr/include/bits

File name table:
 Entry Dir   Time      Size      Name
 1     0     0         0         hello.c
 2     1     0         0         stddef.h
 3     2     0         0         bits/types.h
 4     2     0         0         libio.h
 5     2     0         0         stdio.h
 6     2     0         0         bits/sys_errlist.h

Note that the last directory table entry is never used.
After this patch it looks as follows:

Directory table:
 /opt/local/install/gcc/lib/gcc/x86_64-pc-linux-gnu/8.0.1/include
 /usr/include/bits
 /usr/include

File name table:
 Entry Dir   Time      Size      Name
 1     0     0         0         hello.c
 2     1     0         0         stddef.h
 3     2     0         0         types.h
 4     3     0         0         libio.h
 5     3     0         0         stdio.h

[AArch64] PR target/85512: Tighten SIMD right shift immediate constraints

In this testcase it is possible to generate an invalid SISD shift of zero:
Error: immediate value out of range 1 to 64 at operand 3 -- `sshr v9.2s,v0.2s,0'

The SSHR and USHR instructions require a shift from 1 up to the element size.
However our constraints on the scalar shifts that generate these patterns
allow a shift amount of zero as well. The pure GP-reg ASR and LSR instructions allow a shift amount of zero.

It is unlikely that a shift of zero will survive till the end of compilation, but it's not impossible, as this PR shows.

The patch tightens up the constraints in the offending patterns by adding two new constraints
that allow shift amounts [1,32] and [1,64] and using them in *aarch64_ashr_sisd_or_int_<mode>3
and *aarch64_lshr_sisd_or_int_<mode>3.
The left-shift SISD instructions SHL and USHL allow a shift amount of zero so don't need adjustment
The vector shift patterns that map down to SSHR and USHR already enforce the correct immediate range.

    x86: Enable -fcf-protection with multi-byte NOPs

-fcf-protection no longer depens on -mcet and with revision 259522:

commit d59cfa9a4064339cf2bd2da828c4c133f13e57f0
Author: hjl <hjl@138bc75d-0d04-0410-961f-82ee72b054a4>
Date:   Fri Apr 20 13:30:13 2018 +0000

    Define __CET__ for -fcf-protection and remove -mibt

-mcet becomes an alias for -mshstk.

We can remove -mcet/-mno-cet where they are unused and replace -mcet
with -mshstk where -mcet is used as an alias for -mshstk.
