configure: allow --with-dtrace on freebsd

build: ./configure pass positional args to gyp

use `--` to specify the arguments you want to pass directly to gyp.

for example: `./configure -- --no-parallel -Dsome_define=foo`

fixes #6370

configure: add mips-float-abi (soft, hard) option

configure: fix cross-compilation host_arch_cc()

In case of cross-compilation host_arch_cc() function could return
target arch if CC was set to target arch compiler. Host arch
compiler should always be used in this case. This was broken
by commit 707863c.

configure: respect the --dest-os flag consistently

Consider a user on his Mac, who wants to cross-compile for his Linux ARM device:

./configure --dest-cpu=arm --dest-os=linux

Before this patch, for example, DTrace probes would incorrectly attempt to be...

configure: define "arm_fpu" and "arm_neon" for ARM

v8's common.gypi file expects them to be defined now.

Closes #4534.

build: Add hyphen to custom build tags

so that ./configure --tag=foo makes a version number like v0.9.5-foo
instead of v0.9.5foo

Ease building with VS Express by checking in generated files.

build: make python executable configurable

Upstreamed in https://codereview.chromium.org/11418101/

Fixes #4287.

build: add configure option to generate xcode build files

build: allow linking against system http_parser

build: add --systemtap-includes configure switch

build: let gyp choose msvs version

build: add --unsafe-optimizations configure switch

Turns on -O3 and other optimizations that may produce buggy code with some
toolchains. Use at your own risk.

configure: turn on VFPv3 on ARMv7

Fixes a V8 build error caused by missing arm_fpu and arm_neon settings.

This is a back-port of commit bbf6b4e from the master branch.

Fixes #4142.

configure: always use shlex instead of split

Use shlex module instead of builtin string split to parse CC.

configure: add a "--dest-os" option to force a gyp "flavor"

This makes cross-compiling easier. i.e. from my mac:

./configure --dest-cpu=arm --dest-os=linux

build: add configure option to build with ninja

build: Don't set gcc_version for Windows

build: compile with -fno-tree-vrp when gcc >= 4.0

build: fix mksnapshot crash on sunos

Unconditionally compile V8 with -fno-strict-aliasing on all platforms.

gcc 4.5.2 on sunos generates bad code when -fstrict-aliasing is enabled, which
undoubtedly means that there are more buggy versions of gcc out there....

build: disable unsafe optimizations

Compile at -O2 and disable optimizations that trigger gcc bugs.

Some people still reported mksnapshot crashes after commit b40f813 ("build: fix
spurious mksnapshot crashes for good" - so much for that).

Average performance of the -O2 binary is on par with the -O3 binary. Variance...

Fix the Windows build

build: disable -fstrict-aliasing for any gcc < 4.6.0

It has been conclusively demonstrated that the -fstrict-aliasing bugs in gcc's
optimizer are not limited to the 4.5.x releases only.

Fixes #3601 among others.

build: handle output of localized gcc or clang

Before this commit, we used to scan the output of `$CC -v` for strings like
"gcc version x.y.z".

It was pointed out that this approach fails with localized versions of gcc
because those print (for example) "gcc versión x.y.z"....

build: use proper python interpreter

Make configure start gyp with the same python interpreter that is used to
run configure itself.

Fixes an issue where configure fails with a SyntaxError because the user
has multiple python binaries on his $PATH and the default one is too old.

build: fix --shared-v8 option

build: expand ~ in `./configure --prefix=~/a/b/c`

Rename GYP variable node_use_system_openssl to be consistent

Windows: Enable ETW events.
This commit enables ETW events to be fired on Windows for existing
DTrace probes. ETW instrumentation is enabled by default. It
is possible to build node.exe without ETW instrumentation by
using --without-etw option with configure script.

build: improve c compiler detection

configure: output a newline at the end of config.gypi

build: add support for DTrace and postmortem

• fixes #2110
• includes V8 postmortem metadata in Solaris builds
• adds GYP support for DTrace probes and ustack helper
• ustack helper derives constants dynamically from libv8_base.a
• build with DTrace support by default on SunOS

build: fix configure with spaces in CC

build: disable -fvisibility=hidden if gcc < 4.0.0

build: make CC command in host check configurable

build: remove unused import from configure script

build: remove --shared-cares configure switch

c-ares is a) bundled with libuv now, and b) contains out-of-tree patches. It no
longer makes sense to link against a shared library.

Fixes #2117.

build: support shared zlib

Merge branch 'v0.7.5-release'

build: make default_configuration consistent with BUILDTYPE

build: better host_arch() definition in configure

On one of my OS X Lion machines, it always reports i386, even though 64-bit
is supported. This lookup better matches how WAF determines the host arch,
which was correctly getting 64-bit even on this screwy machine.

build: test `uname -m` first, then `uname -p`

Prevent false i386 on 64-bit OS X.

Revert support for isolates.

It was decided that the performance benefits that isolates offer (faster spin-up
times for worker processes, faster inter-worker communication, possibly a lower
memory footprint) are not actual bottlenecks for most people and do not outweigh...

build: respect --debug configure switch

build: support --dest-cpu configure switch again

GYP: rename options.gypi to config.gypi

Sounds more familiar to unix users used to config.h

--without-npm option

Fixes #2353.

build: DRY configure script

build: auto-run tools/gyp_node after ./configure
