In most cases, we mask lanes which should not trigger exceptions with
a neutral value, then let the existing special-case handler fix them
up later. For exp and exp2 we replace the more complex special-case
handler with a simple scalar fallback. All new behaviour is tested in
runulp.sh, with a new option to pass -f to the run line. We also
extend the fenv testing to Neon log and logf, which already triggered
exceptions correctly. New behaviour is mostly hidden behind a new
config setting, WANT_SIMD_EXCEPT.

- pl/ is built from top-level Makefile by adding pl to SUBS
- PLSUBS lists all pl/ subdirectories that can be built,
it only contains math for now. Please modify this list in
the top-level config.mk.
- pl libraries and infrastructure is built in build/pl/
- As a result math/ and pl/math generate separate test and bench
binaries.
- Use infrastructure provided in math/test to test and profile
pl/math routines. The build system ensures the appropriate
header files are first copied to build/pl/include/test to define
wrappers and entries in ulp and mathbench.
- Copyied scalar erff from math/ to pl/math/ to show build
system is functional.
- pl mathlib libraries are built separately to the main/portable
mathlib libraries and installed alongside.

The outgoing license was MIT only. The new dual license allows
using the code under Apache-2.0 WITH LLVM-exception license too.

Reorganise the makefiles so subprojects can be more separately used and
maintained. Still kept the single toplevel Makefile and config.mk.
Subproject Dir.mk is expected to provide all-X, check-X, clean-X and
install-X targets where X is the subproject name and it may use generic
make variables set in config.mk, like CFLAGS_ALL and CC, or subproject
specific variables like X-cflags.

Not all symbols referenced by mathbench may be available in libc so
link to libmathlib too to resolve the missing symbols.

fenv support is not reliable in clang so provide a mechanism to
disable fenv status checks and only check the result values.
|
|
Users may want different CFLAGS for math and string subprojects, expose
a mechanism for this in config.mk.
|
|
To allow subprojects other than math, the build system and directory
layout is changed: all math related code, tools and tests are under
the math directory now, new subprojects should be similarly self-
contained.
The top level Makefile design is still kept, but the subproject build
directories provide their own Dir.mk with the build rules for the
subproject. The user interface of config.mk is kept for now, in the
future subproject specific flags and make variables may be added for
finer grained control.
