Adding a new ISA extension to RISC-V GCC requires modifying several places:
1. riscv_ext_version_table for the extension version.
2. riscv.opt for the target option and variable.
3. riscv_ext_flag_table to bind the extension to its target option.
4. riscv_combine_info if this extension is just a macro extension.
5. riscv_implied_info if this extension implies other extensions.
6. invoke.texi for documentation (this one is often forgotten - even by me...).
7. riscv-ext-bitmask.def if this extension has been allocated a bitmask in
`__riscv_feature_bits`.
And now, we've integrated all the information into riscv-ext.def and generate
(almost) everything from that!
Some of the fields, like URL, are not used yet. They are planned to be updated
later and used for improving the documentation.
gcc/ChangeLog:
* config/riscv/riscv-ext.def: New file; define extension metadata table.
* config/riscv/riscv-ext-corev.def: New.
* config/riscv/riscv-ext-sifive.def: New.
* config/riscv/riscv-ext-thead.def: New.
* config/riscv/riscv-ext-ventana.def: New.

+Format of DEFINE_RISCV_EXT:
+ NAME:
+ The name of the extension, e.g. "i".
+ UPPERCASE_NAME:
+ The name of the extension in uppercase, e.g. "ZBA", this used
+ for generate TARGET_<ext-name> marco and MASK_<ext-name> macro.
+ For those extension only named with single letter, it should also come with
+ 'RV', e.g. 'v' should use 'RVV' here.
+ Some of old extension like 'i' and 'm' are not follow the rule.
+ FULL_NAME:
+ The full name of the extension, e.g. "Base integer extension".
+ DESC:
+ A short description of the extension, this will used during generating
+ documentation, GNU Texinfo format can be used this field.
+ URL:
+ A URL for the extension.
+ DEP_EXTS:
+ A list of dependent extensions, this is a list of strings or
+ a list of tuples. The first element of the tuple is the name
+ of the extension and the second element is a function that
+ takes a subset_list and returns true if the extension should be added as
+ a dependent extension, `c` and `zca` are examples of this.
+ SUPPORTED_VERSIONS:
+ A list of tuples, each tuple contains the major version number, minor
+ version number and the class of the specification. The version number is a
+ list of integers, e.g. {2, 0} for version 2.0. The class is
+ a string, e.g. "ISA_SPEC_CLASS_20191213", the class of the
+ specification is not required for any new extension.
+ FLAG_GROUP:
+ The group of the extension, this is used to group extensions
+ together. The group is a string, e.g. "base", "zi", "zm", "za", "zf",
+ "zc", "zb", "zk" and "zi".
+ This should be auto generated in theory in some day...
+ BITMASK_GROUP_ID:
+ The group id of the extension for the __riscv_feature_bits.
+ this field should sync with riscv-c-api-doc, and keep
BITMASK_NOT_YET_ALLOCATED
+ if not got allocated.
+
https://github.com/riscv-non-isa/riscv-c-api-doc/blob/main/src/c-api.adoc#extension-bitmask-definitions
+ BITMASK_BIT_POSITION:
+ The bit position of the extension for the __riscv_feature_bits.
+ this field should sync with riscv-c-api-doc, and keep
BITMASK_NOT_YET_ALLOCATED
+ if not got allocated.
+
https://github.com/riscv-non-isa/riscv-c-api-doc/blob/main/src/c-api.adoc#extension-bitmask-definitions
+ EXTRA_EXTENSION_FLAGS:
+ Extra flags for the extension, this is a bitmask of the
+ extra flags. The extra flags are:
+ - EXT_FLAG_MACRO: Set this flag if this extension is just a macro of set of
+ extensions, and not define any new instrcutions, new CSRs or new
+ behaviors, the example is `b` extension is just a macro of `zba`, `zbb`
+ and `zbs`.
