Readable Go Assembly Output
Understanding the assembly code generated by the Go compiler can be crucial for optimizing performance. However, the default output of the -S flag can be difficult to interpret. Here are some methods to make it more accessible:
Output to File:
To save the assembly output to a file instead of printing it to the terminal, use the following command:
go tool compile -S file.go > file.s
Separate Functions with Labels:
To separate out the assembly code into individual functions with labels, disable optimization using the -N flag:
go tool compile -S -N file.go
Using gccgo:
Alternatively, you can leverage gccgo with the following command to generate assembly code in an optimized or unoptimized format:
gccgo -S -O0/1/2/3 -masm=intel test.go
By experimenting with different optimization levels (-O0/1/2/3), you can observe the impact of optimizations on the generated assembly code.
The above is the detailed content of How Can I Make Go Assembly Output More Readable?. For more information, please follow other related articles on the PHP Chinese website!
String Manipulation in Go: Mastering the 'strings' PackageMay 14, 2025 am 12:19 AMMastering the strings package in Go language can improve text processing capabilities and development efficiency. 1) Use the Contains function to check substrings, 2) Use the Index function to find the substring position, 3) Join function efficiently splice string slices, 4) Replace function to replace substrings. Be careful to avoid common errors, such as not checking for empty strings and large string operation performance issues.
Go 'strings' package tips and tricksMay 14, 2025 am 12:18 AMYou should care about the strings package in Go because it simplifies string manipulation and makes the code clearer and more efficient. 1) Use strings.Join to efficiently splice strings; 2) Use strings.Fields to divide strings by blank characters; 3) Find substring positions through strings.Index and strings.LastIndex; 4) Use strings.ReplaceAll to replace strings; 5) Use strings.Builder to efficiently splice strings; 6) Always verify input to avoid unexpected results.

How to use the 'strings' package to manipulate strings in Go step by stepMay 13, 2025 am 12:12 AMGo's strings package provides a variety of string manipulation functions. 1) Use strings.Contains to check substrings. 2) Use strings.Split to split the string into substring slices. 3) Merge strings through strings.Join. 4) Use strings.TrimSpace or strings.Trim to remove blanks or specified characters at the beginning and end of a string. 5) Replace all specified substrings with strings.ReplaceAll. 6) Use strings.HasPrefix or strings.HasSuffix to check the prefix or suffix of the string.
Go strings package: how to improve my code?May 13, 2025 am 12:10 AMUsing the Go language strings package can improve code quality. 1) Use strings.Join() to elegantly connect string arrays to avoid performance overhead. 2) Combine strings.Split() and strings.Contains() to process text and pay attention to case sensitivity issues. 3) Avoid abuse of strings.Replace() and consider using regular expressions for a large number of substitutions. 4) Use strings.Builder to improve the performance of frequently splicing strings.
What are the most useful functions in the GO bytes package?May 13, 2025 am 12:09 AMGo's bytes package provides a variety of practical functions to handle byte slicing. 1.bytes.Contains is used to check whether the byte slice contains a specific sequence. 2.bytes.Split is used to split byte slices into smallerpieces. 3.bytes.Join is used to concatenate multiple byte slices into one. 4.bytes.TrimSpace is used to remove the front and back blanks of byte slices. 5.bytes.Equal is used to compare whether two byte slices are equal. 6.bytes.Index is used to find the starting index of sub-slices in largerslices.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
