Right now `-fno-exception` will be in `cflags` for every executable.
That prevents adding & building 3rd party `DEPS` that may use

So we'll remove `-fno-exceptions` from global configurations and rely on
the fact that the `dart_config` GN config already has `-fno-exceptions`

To avoid these flags being applied to unexpected build rules, we
separate them out into a separate config that is then pulled in
explicitly in the `dart_precompiled_runtime{,_product}` executable
rules. Only those two executables need the additional empty section:
the product version because it becomes `dartaotruntime` in the SDK
bundle, and the non-product version because some of our tests build
standalone executables using it.
The linker flags were originally removed due to
https://github.com/flutter/flutter/issues/112687.

To create a Dart standalone executable on MacOS, we modify the
dartaotruntime executable to add the snapshot contents, and the
VM looks into the executable on disk to find the snapshot to load.
Previously, we did this by adding a new 64-bit segment load command
with a single section, where the section's file offset and size
describes the inserted snapshot. This meant the Mach-O header size increased by 152 bytes.
Originally, this wasn't an issue as there was plenty of padding, but
later clang updates removed most of this padding, and so writing the
new header actually overwrote the initial contents of the first section
in the file, which happens to be the __text section. In addition, since
the first section's offset was now declared to be within the header,
utilities that strictly validated the Mach-O format, like codesign,
would report errors.
This CL changes it so that we actually reserve space in the
dartaotruntime header using the -add_empty_section flag to the linker.
In addition, we change from using a segment load command to using a
(40 byte) note load command. This is because a segment load command
specifies that the contents should be loaded in memory, but we don't
use that loaded version. Instead, the VM reloads it from the executable
on disk so it can appropriately mmap the different parts of the
snapshot. A note section instead just declares a section of the
executable as arbitrary data that the owner can read from the file
and use as desired, which is semantically closer to our current usage.
This CL also adds a test to pkg/dartdev/test/commands/compile_test to
ensure that corrupting a random part of the snapshot in the executable
causes signature verification to fail.
This CL also reverts CL 256208, thus relanding the clang changes
starting from June that originally raised awareness of the issue by
greatly reduced the amount of padding after the load commands.

Implements a backend targeting RV32GC and RV64GC, based on Linux standardizing around GC. The assembler is written to make it easy to disable usage of C, but because the sizes of some instruction sequences are compile-time constants, an additional build configuration would need to be defined to make use of it.
The assembler and disassembler cover every RV32/64GC instruction. The simulator covers all instructions except accessing CSRs and the floating point state accessible through such, include accrued exceptions and dynamic rounding mode.
Quirks:
- RISC-V is a compare-and-branch architecture, but some existing "architecture-independent" parts of the Dart compiler assume a condition code architecture. To avoid rewriting these parts, we use a peephole in the assembler to map to compare-and-branch. See Assembler::BranchIf. Luckily nothing depended on taking multiple branches on the same condition code set.
- There are no hardware overflow checks, so we must use Hacker's Delight style software checks. Often these are very cheap: if the sign of one operand is known, a single branch is needed.
- The ranges of RISC-V branches and jumps are such that we use 3 levels of generation for forward branches, instead of the 2 levels of near and far branches used on ARM[64]. Nearly all code is handled by the first two levels with 20-bits of range, with enormous regex matchers triggering the third level that uses aupic+jalr to get 32-bits of range.
- For PC-relative calls in AOT, we always generate auipc+jalr pairs with 32-bits of range, so we never generate trampolines.
- Only a subset of registers are available in some compressed instructions, so we assign the most popular uses to these registers. In particular, THR, TMP[2], CODE and PP. This has the effect of assigning CODE and PP to volatile registers in the C calling convention, whereas they are assigned preserved registers on the other architectures. As on ARM64, PP is untagged; this is so short indices can be accessed with a compressed instruction.
- There are no push or pop instructions, so combining pushes and pops is preferred so we can update SP once.
- The C calling convention has a strongly aligned stack, but unlike on ARM64 we don't need to use an alternate stack pointer. The author ensured language was added to the RISC-V psABI making the OS responsible for realigning the stack pointer for signal handlers, allowing Dart to leave the stack pointer misaligned from the C calling convention's point of view until a foreign call.
- We don't bother with the link register tracking done on ARM[64]. Instead we make use of an alternate link register to avoid inline spilling in the write barrier.
Unimplemented:
- non-trivial FFI cases
- Compressed pointers - No intention to implement.
- Unboxed SIMD - We might make use of the V extension registers when the V extension is ratified.
- BigInt intrinsics

The current script stores some environment variable values as GN declarations.
It replaces `"` inside the value with `\"` because it creates a `"`-delimited
string, but it doesn't replace `\` with `\\` as it rightly should to preserve
the meaning of the original string.
That affects **Windows paths**. If your path ends in `\`, the created "string literal"
will end (or rather, not end) with `\"` and not be valid.
Similarly if it contains `\"` originally, it will become `\\"` and end the string

It's easy to have a path ending in something like `C:\something\something\`,
and you can't compile Dart if you have that.

This removes warnings like these:
```
ld: warning: object file (../../buildtools/mac-x64/clang/bin/../lib/libc++.a(memory.cpp.o)) was built for newer OSX version (10.13) than being linked (10.8)
```
These warnings seem to be harmless but may indicate that our builds are
no longer working below macOS 10.13. On developer machines, these
warnings don't seem to occur. We don't test on versions older than 10.13
so we can't guarantee that the Dart SDK works on those.

Convert dart BUILD.gn rules to manually filter the files that
are build using explicit `if` expressions. Remove obsolete call
to set_sources_assignment_filter() to filter '*_test.*' files
as no such files are present in the variables used to build the

Several people have experienced build issues traced back to
target `//utils/dartanalyzer:generate_summary_strong`.
The issue is triggered by the sdk_hash changing with an old
kernel-service snapshot in the out/ folder.
`generate_summary_strong` uses but does not explicitly depend on
the kernel-service, causing the outdated dependency.
This then causes 'Unexpected Kernel SDK Version' when the new dart
binary tried to load the old kernel-service snapshot.
Tested:
1. Clean build of create_sdk at HEAD.
2. Empty `git commit --amend` to modify commit and thus sdk hash.
3. Rebuild of create_sdk (which failed before).

Also, GDB cannot debug position-independent executables in QEMU, so we disable

This treats whether or not to use the forked NNBD SDK as a build flag
similar to mode or architecture. When this flag is passed, it appends
"NNBD" to the main output directory, like xcodebuild/ReleaseX64NNBD.
It also defines a "use_nnbd" flag that is available inside BUILD.gn
files to determine whether or not to use the forked SDK. This flag
currently isn't used. Implementation teams will need to edit their
build steps to take that into account.
In order to use this mode on the bots, we'll need to tweak the bot
scripts to figure out whether the mode is enabled or not. There are a
couple of TODOs in the Python scripts for that. I'm not sure how that
should be specified in dart_sdk.py.
This CL does not remove my previous change to allow building the NNBD
fork next to dart-sdk in the same root output directory. I'll revert
those changes in a different CL once this one lands.

This work pulls in v8 support for these features with
appropriate changes for Dart and closes
https://github.com/dart-lang/sdk/issues/34935.
This adds support for the following features:
* Interpreting patterns as Unicode patterns instead of
BMP patterns
* the dotAll flag (`/s`) for changing the behavior
of '.' to also match line terminators
* Escapes for character classes described by Unicode
property groups (e.g., \p{Greek} to match all Greek
characters, or \P{Greek} for all non-Greek characters).
The following TC39 proposals describe some of the added features:
* https://github.com/tc39/proposal-regexp-dotall-flag
* https://github.com/tc39/proposal-regexp-unicode-property-escapes
These additional changes are included:
* Extends named capture group names to include the full
range of identifier characters supported by ECMAScript,
not just ASCII.
* Changing the RegExp interface to return RegExpMatch
objects, not Match objects, so that downcasting is
not necessary to use named capture groups from Dart
**Note**: The changes to the RegExp interface are a
breaking change for implementers of the RegExp interface.
Current users of the RegExp interface (i.e., code using Dart
RegExp objects) will not be affected.

Right now most of the dart SDK's python is compatible with python2
or python3. This change fixes a few of the build scripts to make
that completely true (at least when building the standard build on
Linux). There are only four types of changes:
- Bare `print` statements now use the `print ()` function
- `commands.getoutput` becomes `subprocess.check_output` with `shell=True`
- `xrange` becomes `range`
- `print >> sys.stderr` becomes `sys.stderr.write`
Starts work on addressing (but does not completely fix):

The 7zip dependency is only used on Windows. Use gclient's OS-specific
hook feature to only download it while on Windows. This avoids the
download from google cloud storage from needlessly saying it is doing
nothing.
There's no reason to point out the sysroot is already up to date as this
makes gclient output several lines of text with zero information.

Wheezy is not supported anymore (EOL May 2018) and these sysroots are
really outdated, which introduces build problems whenever we try to
use recent enough features and header files.
We are already using Jessie to build Dart SDK distributions and in some cases we use
Jessie to build binaries for testing (e.g. when building on ARM64).
This CL makes it uniform.

dart binary would instantiate CrashpadClient if DART_CRASHPAD_HANDLER
and DART_CRASHPAD_CRASHES_DIR environment variables are set.
- DART_CRASHPAD_HANDLER should contain the path to the crashpad_handler
binary that would handle the crash and write minidump;
- DART_CRASHPAD_CRASHES_DIR should contain the path to the crashpad database
which would be used to store minidumps.
Rewrite --copy-crash-dumps support on windows to use Crashpad integration
instead of editing Windows registry.
Embedding crashpad required to roll a new zlib version because Crashpad
depends on the zlib. This version of zlib is buildable with its own
BUILD.gn so our custom BUILD.gn is removed.
