How Can I Remove File Paths from Go Binaries Using the `-trimpath` Flag?

Eliminating File Paths in go Binaries with TEXT Directives

To remove file paths like "/Users/myuser/dev/go/src/fooapi/spikes/mongoapi.go" from go executables, employ the -trimpath flag as follows:

CGO_ENABLED=0 go build -v -a -ldflags="-w -s" \
    -gcflags=-trimpath=/Users/myuser/dev/go/src \
    -asmflags=-trimpath=/Users/myuser/dev/go/src \
    -o ./fooapi spikes/mongoapi.go

Mechanism of -trimpath:

The -trimpath flag passed to both -gcflags and -asmflags removes specified prefixes from recorded source file paths in the elf binary.

Result Verification:

Execute go tool objdump ./fooapi to view the modified result:

$ go tool objdump ./fooapi

.
.
TEXT main.init(SB) api/spikes/mongoapi.go
mongoapi.go:60  0x12768c0   65488b0c25a0080000  GS MOVQ GS:0x8a0, CX
mongoapi.go:60  0x12768c9   483b6110        CMPQ 0x10(CX), SP
mongoapi.go:60  0x12768cd   7663            JBE 0x1276932
