+# Because the workspace is a volume, filesystem changes are persisted between

-If hardware lacks basic or specialized functionality, compiler-rt adds such functionality
-for basic arithmetic(s).
-One such example is 64-bit integer multiplication on 32-bit x86.
-
-Goals:
-1. zig as linker for object files produced by other compilers
-   => `function compatibility` to compiler-rt and libgcc for same-named functions
-   * compatibility conflict between compiler-rt and libgcc: prefer compiler-rt
-2. `symbol-level compatibility` low-priority compared to emitted calls by llvm
-   * symbol-level compatibility: libgcc even lower priority
-3. add zig-specific language runtime features, see #7265
-   * example: arbitrary bit width integer arithmetic
-   * lower to call those functions for e.g. multiplying two i12345 numbers together
-   * proper naming + documention for standardizing (allow languages to follow our exmaple)
-
-Current status (tracking libgcc documentation):
-- Integer library routines => almost implemented
-- Soft float library routines => finished
-- Decimal float library routines => unimplemented (~120 functions)
-- Fixed-point fractional library routines => unimplemented (~300 functions)
-- Exception handling routines => unclear, if supported (~32+x undocumented functions)
-- Miscellaneous routines => unclear, if supported (cache control and stack function)
-- No zig-specific language runtime features in compiler-rt yet
-
-This library is automatically built as-needed for the compilation target and
-then statically linked and therefore is a transparent dependency for the
-programmer.
-For details see `../compiler_rt.zig`.
-
-The routines in this folder are listed below.
-Routines are annotated as `type source routine // description`, with `routine`
-being the name used in aforementioned `compiler_rt.zig`.
-`dev` means deviating from compiler_rt, `port` ported, `source` is the
-information source for the implementation, `none` means unimplemented.
-Some examples for the naming convention are:
-- dev source name_routine, name_routine2 various implementations for performance, simplicity etc
-- port llvm compiler-rt library routines from [LLVM](http://compiler-rt.llvm.org/)
-   * LLVM emits library calls to compiler-rt, if the hardware lacks functionality
-- port musl libc routines from [musl](https://musl.libc.org/)
-If the library or information source is uncommon, use the entry `other` for `source`.
-Please do not break the search by inserting entries in another format than `impl space source`.
-
-Bugs should be solved by trying to duplicate the bug upstream, if possible.
- * If the bug exists upstream, get it fixed upstream and port the fix downstream to Zig.
- * If the bug only exists in Zig, use the corresponding C code and debug
-   both implementations side by side to figure out what is wrong.

-## Decimal float library routines

-BID means Binary Integer Decimal encoding, DPD means Densely Packed Decimal encoding.
-BID should be only chosen for binary data, DPD for decimal data (ASCII, Unicode etc).
-If possible, use BCD instead of DPD to represent numbers not accurately representable
-in binary like the number 0.2.

-All routines are TODO.
