-    compiler/cmm/PprC.hs: constify local string literals
-    
-    Consider one-line module
-        module B (v) where v = "hello"
-    in -fvia-C mode it generates code like
-        static char gibberish_str[] = "hello";
-    
-    It uselessly eats data section (precious resource on ia64!).
-    The patch switches genrator to emit:
-        static const char gibberish_str[] = "hello";
-

-    powerpc: fix and enable shared libraries by default on linux
-    
-    Summary:
-    And fix things all the way down to it. Namely:
-        - remove 'r30' from free registers, it's an .LCTOC1 register
-          for gcc. generated .plt stubs expect it to be initialised.
-        - fix PicBase computation, which originally forgot to use 'tmp'
-          reg in 'initializePicBase_ppc.fetchPC'
-        - mark 'ForeighTarget's as implicitly using 'PicBase' register
-          (see comment for details)
-        - add 64-bit MO_Sub and test on alloclimit3/4 regtests
-        - fix dynamic label offsets to match with .LCTOC1 offset
-    
-    Signed-off-by: Sergei Trofimovich <siarheit@google.com>

-    Test Plan: validate passes equal amount of vanilla/dyn tests

-    GhcMake: limit Capability count to CPU count in parallel mode
-    
-    In Trac #9221 one of problems using high --jobs=<N>
-    is amount of mutator (or GC) threads we crate.
-    
-    We use userspace spinning-and-yielding (see ACQUIRE_SPIN_LOCK)
-    to acess work stealing queues. In case of
-    N-worker-threads > N-CPUs fraction of time when
-    thread holding spin lock gets descheduled by kernel
-    increases. That causes other threads to waste CPU time
-    before giving up CPU.
-    
-    Signed-off-by: Sergei Trofimovich <siarheit@google.com>
-    
-    Test Plan:
-    ghc --make -j8 and -j80 have comparable sys time
-    on a 8-core system.

-    rts: enable parallel GC scan of large (32M+) allocation area
-    
-    Parallel GC does not scan large allocation area (-A)
-    effectively as it does not do work stealing from nursery
-    by default.
-    
-    That leads to large imbalance when only one of threads
-    overflows allocation area: most of GC threads finish
-    quickly (as there is not much to collect) and sit idle
-    waiting while single GC thread finishes scan of single
-    allocation area for that thread.
-    
-    The patch enables work stealing for (equivalent of -qb0)
-    allocation area of -A32M or higher.
-    
-    Tested on a highlighting-kate package from Trac #9221
-    
-    On 8-core machine the difference is around 5% faster
-    of wall-clock time. On 24-core VM the speedup is 20%.

-    restore -fmax-worker-args handling (Trac #11565)
-    
-    maxWorkerArgs handling was accidentally lost 3 years ago
-    in a major update of demand analysis
-        commit 0831a12ea2fc73c33652eeec1adc79fa19700578
-    
-    Old regression is noticeable as:
-    - code bloat (requires stack reshuffling)
-    - compilation slowdown (more code to optimise/generate)
-    - and increased heap usage (DynFlags unboxing/reboxing?)
-    
-    On a simple compile benchmark this change causes heap
-    allocation drop from 70G don to 67G (ghc perf build).

-Subject: [PATCH] Compute DW_FORM_block length correctly; also fixes #15068
-
-Before this patch, the pprUnwindwExpr function computed the length of
-by the following assembly fragment:
-
-	.uleb128 1f-.-1
-	<expression data>
-1:
-
-That is, to compute the length, it takes the difference of the label 1
-and the address of the .uleb128 directive, and subtracts 1.
-
-In #15068 it was reported that `as` from binutils 4.30 has trouble with
-evaluating the `.` part of the expression. However, there is actually a
-problem with the expression, if the length of the data ever becomes
-larger than 128: In that case, the .uleb128 directive will emit more
-than 1 byte, and the computed length will be wrong.
-
-The present patch changes the assembly fragment to use two labels,
-which fixes both these problems.
-
-	.uleb128 2f-1f

-	<expression data>

-Subject: [PATCH] compiler/cmm/PprC.hs: constify labels in .rodata
-
-Summary:
-Consider one-line module
-    module B (v) where v = "hello"
-in -fvia-C mode it generates code like
-    static char gibberish_str[] = "hello";
-
-It resides in data section (precious resource on ia64!).
-The patch switches genrator to emit:
-    static const char gibberish_str[] = "hello";
-
-Other types if symbols that gained 'const' qualifier are:
-
-- info tables (from haskell and CMM)
-- static reference tables (from haskell and CMM)
-
-Cleanups along the way:
-
-- fixed info tables defined in .cmm to reside in .rodata
-- split out closure declaration into 'IC_' / 'EC_'
-- added label declaration (based on label type) right before
-  each label definition (based on section type) so that C
-  compiler could check if declaration and definition matches
-  at definition site.

-    cross-build 'unlit' and 'hp2ps' for stage2 install
-    
-    In navive build case it does not matter much if we build
-    'unlit' and 'hp2ps' tools with ghc-stage0 or ghc-stage1:
-    both GHCs are native compilers and both tools are written
-    in C (have no haskell code).
-    
-    But in cross-case the difference is substantial:
-    In Stag1Only=YES case we need to install native tools built
-    by ghc-stage0/${host}-cc.
-    In Stag1Only=NO  case we need to install cross-built tools
-    built by ghc-stage1/${target}-cc.
-    
-    Before this change GHC did not have a rule to build cross-built
-    'unlit' and 'hp2ps'.
-    
-    The change adds cross-built 'unlit' and 'hp2ps' as 'dist-install'
-    targets.
-    
-    'inplace/lib/bin/unlit.bin' target is unchanged and still contains
-    native binary.
-    
-    As a result this change allows cross-building and packaging whole
-    GHC for target platform!

-    fix 'make install' for cross-stage2
-    
-    When cross-built GHC is being installed one of
-    latest steps is to register installed libraries
-    with 'ghc-pkg'.
-    
-    GHC uses freshly installed 'ghc-pkg' and 'ghc-stage2'
-    for that.
-    
-    Tested as:
-        ./configure --target=aarch64-unknown-linux-gnu
-        make install DESTDIR=$(pwd)/__s2 STRIP_CMD=:
-    
-    Before the change install failed on ghc-pkg execution phase:
-    
-        ".../ghc-cross/__s2/usr/local/lib/ghc-8.3.20170406/bin/ghc-pkg" \
-            --force \
-            --global-package-db \
-            ".../ghc-cross/__s2/usr/local/lib/ghc-8.3.20170406/package.conf.d" \
-            update rts/dist/package.conf.install
-        /bin/sh: .../ghc-cross/__s2/usr/local/lib/ghc-8.3.20170406/bin/ghc-pkg: \
-            No such file or directory
-    
-    To avoid breakage we use 'ghc' and 'ghc-pkg' built by stage0.

-    avoid $(CrossCompilerPrefix) for stage2 install
-    
-    Suppose we are crossbuilding ghc (when ghc-stage2
-    is a normal compiler for $target):
-    
-    For this case 'make install' should install unprefixed
-    stage2 'ghc' and not '$(CorssCompilePrefix)-ghc'.
-    
-    That way cross-built ghc is installable and
-    usable on target as if it would be built natively
-    on a target.

-Subject: [PATCH] aclocal.m4: allow arbitrary <vendor> string in toolchain
- triplets
-
-Canonical triplets have a form of
-    <arch>-<vendor>-<os>[-<abi>]
-
-Checking for vendor is almost never correct as it's an
-arbitrary string.
-
-It's useful to have multiple "vendors" to denote
-otherwise the same (WRT <arch>, <os>, <abi>) target:
-    --target=x86_64-pc-linux-gnu
-    --target=x86_64-unknown-linux-gnu
-    --target=x86_64-ghc80-linux-gnu
-    --target=x86_64-ghchead-linux-gnu
-
-Do not fail unknown vendors. Only emit a warning.
-Ideally configure checks should never use "vendor".
-
