The existing implementation fails to determine the correct time zone abbreviations when the display language is non-English. This change adds support for localized time zone names (standard- and daylightname) by using the function RegLoadMUIString.

Previously t.zero always pointed to runtime.zerovalue. Change the hashmap code to always return a runtime pointer directly, and change that pointer to point to a larger buffer if one is needed. (It might be better to only copy from the pointer returned by the mapaccess functions when the value type is small enough and have the compiler insert explicit zeroing for larger value types, but I tried and failed to do this). This removes all uses of the zero field of the type data; the field itself can be removed in a separate change.

This was always a bit confusing, but it also fixes a problem: runtime.firstmoduledata was always overridden in the linker to be a local symbol but cmd/internal/obj had already rewritten code accessing it to access it via the GOT. This works on amd64, but causes link failures on other platforms (e.g. arm64). Change-Id: I9b8153af74b4d0f092211d63a000d15818f39773 Reviewed-on: https://go-review.googlesource.com/13786Reviewed-by:

The issue 12226 has been caused by the allocation of the same register for the equality check of two byte values. The code in cgen.go freed the register for the second operand before the allocation of the register for the first operand.

Austin Clements authored
A comparison of the form l == r where l is an interface and r is concrete performs a type assertion on l to convert it to r's type. However, the compiler fails to zero the temporary where the result of the type assertion is written, so if the type is a pointer type and a stack scan occurs while in the type assertion, it may see an invalid pointer on the stack. Fix this by zeroing the temporary. This is equivalent to the fix for type switches from c4092ac3. Fixes #12253.

Add benchmarks for for sparsely escaped and densely escaped strings. Then speed up the sparse unescaping part heavily by using IndexByte and copy to skip the parts containing no escaping very fast. Unescaping densely escaped strings slower because of the new function call overhead. But sparsely encoded strings are seen more often in the utf8 enabled web. We win part of the speed back by looking up entityName differently. benchmark old ns/op new ns/op delta BenchmarkEscape 31680 31396 -0.90% BenchmarkEscapeNone 6507 6872 +5.61% BenchmarkUnescape 36481 48298 +32.39% BenchmarkUnescapeNone 332 325 -2.11% BenchmarkUnescapeSparse 8836 3221 -63.55% BenchmarkUnescapeDense 30639 32224 +5.17% Change-Id: If606cb01897a40eefe35ba98f2ff23bb25251606 Reviewed-on: https://go-review.googlesource.com/10172Reviewed-by:

The current implementations of MarshalJSON and MarshalText use time.Format which returns a string (converted from a byte slice), only to convert it back to a byte slice. Avoid the conversion (and thus an allocation) by directly appending the formatted time to a preallocated byte slice, using the new AppendFormat function, introduced in golang.org/cl/1760. This reduces the allocations done in Marshal[Text|JSON] by 50%. benchmark old ns/op new ns/op delta BenchmarkMarshalJSON 626 507 -19.01% BenchmarkMarshalText 598 511 -14.55% benchmark old allocs new allocs delta BenchmarkMarshalJSON 2 1 -50.00% BenchmarkMarshalText 2 1 -50.00% benchmark old bytes new bytes delta BenchmarkMarshalJSON 96 48 -50.00% BenchmarkMarshalText 96 48 -50.00% Fixes #11025 Change-Id: I468f78d075a6ecc1cdc839df7fb407fbc6ff2e70 Reviewed-on: https://go-review.googlesource.com/10555Reviewed-by:
