2023-06-23compiler, libgo: support bootstrapping gc compilerIan Lance Taylor1-8/+2
In the Go 1.21 release the package internal/profile imports internal/lazyregexp. That works when bootstrapping with Go 1.17, because that compiler has internal/lazyregep and permits importing it. We also have internal/lazyregexp in libgo, but since it is not installed it is not available for importing. This CL adds internal/lazyregexp to the list of internal packages that are installed for bootstrapping. The Go 1.21, and earlier, releases have a couple of functions in the internal/abi package that are always fully intrinsified. The gofrontend recognizes and intrinsifies those functions as well. However, the gofrontend was also building function descriptors for references to the functions without calling them, which failed because there was nothing to refer to. That is OK for the gc compiler, which guarantees that the functions are only called, not referenced. This CL arranges to not generate function descriptors for these functions.

2023-06-16libgo/testsuite: add benchmarks and examples to listIan Lance Taylor1-0/+9
In CL 384695 I simplified the code that built lists of benchmarks, examples, and fuzz tests, and managed to break it. This CL corrects the code to once again make the benchmarks available, and to run the examples with output and the fuzz targets. Doing this revealed a test failure in internal/fuzz on 32-bit x86: a signalling NaN is turned into a quiet NaN on the 387 floating-point stack that GCC uses by default. This CL skips the test.

2020-10-13reflect: ensure uniqueness of type descriptors on AIX.Clément Chigot3-4/+42
On AIX, duplication of type descriptors can occur if one is declared in the libgo and one in the Go program being compiled. The AIX linker isn't able to merge them together as Linux one does. One solution is to always load libgo first but that needs a huge mechanism in gcc core. Thus, this patch ensures that the duplication isn't visible for the end user. In reflect and internal/reflectlite, the comparison of rtypes is made on their name and not only on their addresses. In reflect, toType() function is using a canonicalization map to force rtypes having the same rtype.String() to return the same Type. This can't be made in internal/reflectlite as it needs sync package. But, for now, it doesn't matter as internal/reflectlite is not widely used.

2020-01-02compiler, runtime, reflect: generate hash functions only for map keysIan Lance Taylor1-30/+10
Right now we generate hash functions for all types, just in case they are used as map keys. That's a lot of wasted effort and binary size for types which will never be used as a map key. Instead, generate hash functions only for types that we know are map keys. Just doing that is a bit too simple, since maps with an interface type as a key might have to hash any concrete key type that implements that interface. So for that case, implement hashing of such types at runtime (instead of with generated code). It will be slower, but only for maps with interface types as keys, and maybe only a bit slower as the aeshash time probably dominates the dispatch time. Reorg where we keep the equals and hash functions. Move the hash function from the key type to the map type, saving a field in every non-map type. That leaves only one function in the alg structure, so get rid of that and just keep the equal function in the type descriptor itself. While we're here, reorganize the rtype struct to more closely match the gc version. This is the gofrontend version of https://golang.org/cl/191198.
