2020-08-17runtime: revert eqtype for AIXClément Chigot9-10/+43
AIX linker is not able to merge identical type descriptors in a single symbol if there are coming from different object or shared object files. This results into several pointers referencing the same type descriptors. Thus, eqtype is needed to ensure that these different symbols will be considered as the same type descriptor. Fixes golang/go#39276 gcc/go/ChangeLog: * go-c.h (struct go_create_gogo_args): Add need_eqtype field. * go-lang.c (go_langhook_init): Set need_eqtype.

2020-08-17compiler: delete lowered constant stringsIan Lance Taylor2-2/+9
If we lower a constant string operation in a Binary_expression, delete the strings. This is safe because constant strings are always newly allocated. This is a hack to use much less memory when compiling the new time/tzdata package, which has a file that contains the sum of over 13,000 constant strings. We don't do this for numeric expressions because that could cause us to delete an Iota_expression. We should have a cleaner approach to memory usage some day. Fixes PR go/96450

2020-08-17compiler,runtime: pass only ptr and len to some runtime callsIan Lance Taylor3-35/+40
This ports https://golang.org/cl/227163 to the Go frontend. This is a step toward moving up to the go1.15rc1 release. Original CL description: cmd/compile,runtime: pass only ptr and len to some runtime calls Some runtime calls accept a slice, but only use ptr and len. This change modifies most such routines to accept only ptr and len. After this change, the only runtime calls that accept an unnecessary cap arg are concatstrings and slicerunetostring. Neither is particularly common, and both are complicated to modify. Negligible compiler performance impact. Shrinks binaries a little. There are only a few regressions; the one I investigated was due to register allocation fluctuation. Passes 'go test -race std cmd', modulo golang/go#38265 and golang/go#38266.

2020-08-17compiler: for package-scope "a = b; b = x" just set "a = x"Ian Lance Taylor2-8/+31
This avoids requiring an init function to initialize the variable. This can only be done if x is a static initializer. The go1.15rc1 runtime package relies on this optimization. The package has a variable "var maxSearchAddr = maxOffAddr". The maxSearchAddr variable is used by code that runs before package initialization is complete.

2020-08-17compiler: scan all function literals for escape analysisIan Lance Taylor2-12/+19
We were scanning only function literals with closures, but not all function literals have closures. Discovered because compiler failed building 1.15rc1, as there is a function literal in the runtime package (p1 in hexdumpWords) that has no closure and, without escape analysis, was forcing a variable to the heap which is not permitted in the runtime.
