haskell - 在 GHC 的堆分析器文件中显示全名

Question

我试图了解 GHC 的堆分析文件。但是名字被缩短了。

JOB "tutd -d db +RTS -h -s -p"
DATE "Thu Oct 21 09:02 2021"
SAMPLE_UNIT "seconds"
VALUE_UNIT "bytes"
BEGIN_SAMPLE 0.000000
END_SAMPLE 0.000000
BEGIN_SAMPLE 0.095057
(3622)decodeCurrent/Project...  96
(2781)parseArgs/opts/crRead...  48
(3824)calculateMerkleHash.d...  24
(2583)main      16
(2848)readGraphTransactionI...  48
(2843)openLockFile/setupDat...  16
(2782)parsePersistenceStrat...  16
(3606)validateMerkleHashes/...  32

有什么办法可以扩展吗？我在UserGuide/Profiling中找不到它。

成本中心的全名在 dot prof 文件中。我可以通过查询否获得更多信息。
