2023-08-03runtime,runtime/pprof: get memory mappings on darwin.Cosmos Nicolaou
Displaying assembly language has never worked for Apple Silicon macs (see #50891). This change uses mach_vm_region to obtain the necessary VM mappings to allow for locating assembly instructions for a cpu profile.

2016-05-31runtime/pprof, cmd/pprof: fix profiling for PIEIan Lance Taylor
In order to support pprof for position independent executables, pprof needs to adjust the PC addresses stored in the profile by the address at which the program is loaded. The legacy profiling support which we use already supports recording the GNU/Linux /proc/self/maps data immediately after the CPU samples, so do that. Also change the pprof symbolizer to use the information, if available, when looking up addresses in the Go pcline data. Fixes #15714.

2016-03-01all: make copyright headers consistent with one space after periodBrad Fitzpatrick
This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.

2014-10-29cmd/objdump: use cmd/internal/objfileRuss Cox
This removes a bunch of ugly duplicate code. The end goal is to factor the disassembly code into cmd/internal/objfile too, so that pprof can use it, but one step at a time. LGTM=r, iant R=r, alex.brainman, iant CC=golang-codereviews https://golang.org/cl/149400043
2014-08-07cmd/addr2line, cmd/nm: factor object reading into cmd/internal/objfileRuss Cox
To do in another CL: make cmd/objdump use cmd/internal/objfile too. There is a package placement decision in this CL: cmd/internal/objfile instead of internal/objfile. I chose to put internal under cmd to make clear (and enforce) that no standard library packages should use this (it's a bit dependency-heavy).
