Use this flag when GOEXPERIMENT=fieldtrack is set. 88 -libgcc file 89 Set name of compiler support library. 90 This is only used in internal link mode. 91 If not set, default value comes from running the compiler, 92 which may be set by the -extld option. 93 Set to "none" to use no support library. 94 -linkmode mode 95 Set link mode (internal, external, auto). 96 This sets the linking mode as described in cmd/cgo/doc.go. 97 -linkshared 98 Link against installed Go shared libraries (experimental). 99 -memprofile file 100 Write memory profile to file. 101 -memprofilerate rate 102 Set runtime.MemProfileRate to rate. 103 -msan 104 Link with C/C++ memory sanitizer support. 105 -o file 106 Write output to file (default a.out, or a.out.exe on Windows). 107 -pluginpath path 108 The path name used to prefix exported plugin symbols. 109 -r dir1:dir2:... 110 Set the ELF dynamic linker search path. 111 -race 112 Link with race detection libraries. 113 -s 114 Omit the symbol table and debug information. 115 -tmpdir dir 116 Write temporary files to dir. 117 Temporary files are only used in external linking mode. 118 -v 119 Print trace of linker operations. 120 -w 121 Omit the DWARF symbol table. 122 */ 123 package link
