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

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.
