To: libc-alpha
Reformats to match style of other hand coded assembly files.
The changes are:
1. Replace 8x space with tab before instructions.
2. After instruction len < 8 use tab.
3. After instruction len >= 8 use space.
4. 1 Space after comma between instruction operands.
5. Indent comments similiar with code.
6. Make comments complete sentences.
7. Tab after '#define'
8. Spaces at '#' representing the depth.
The final executable is unchanged by this commit.

The changes for this patch where made with the following
script: https://github.com/goldsteinn/assembly-beautifier
The goal of this patch is just to reformat the code
so it is more human friendly and try create a style
that future patches will be based on.
If this patch is accepted ensuing patches to
optimize the performance of svml_s_atanhf16_core_avx512.S
will be based on this patch.

The changes are: 1. Replace 8x space with tab before instructions. 2. After instruction len < 8 use tab. 3. After instruction len >= 8 use space. 4. 1 Space after comma between instruction operands. 5. Indent comments similiar with code. 6. Make comments complete sentences. 7. Tab after '#define' 8. Spaces at '#' representing the depth.

Like the idea. How does the following sound: == x86 GAS (Assembly) == The following are stylistic conventions for x86 GAS contributions. Other style conventions that are relevant to x86 GAS syntax are also included (i.e column limit, indenting preprocessor directives, etc..). 1. Instructions should be proceeded by a tab. 2. Instruction less than 8 characters in length should have a tab between it and the first operand. 3. Instruction greater than 7 characters in length should have a space between it and the first operand. 4. There should be a space after the comma seperating operands. For example for rules 1, 2, 3, and 4: ``` /* <tab><short instruction><tab><op0><comma><space><op1>. */ addl $1, %eax /* <tab><long instruction><space><op0><comma><space><op1>. */ vpmovmaskb %ymm0, %eax ``` 5. Comments should be indented with code: For example for rule 5: ``` /* Function XYZ returns. */ ENTRY(XYZ) /* Return from XYZ. */ ret END(XYZ) ``` 6. Tab after `#define`d names and their value. For example: ``` /* No value for 'HELLO' so no tab afterwards. */ #define HELLO /* Value for 'WORLD' so tab separated 'WORLD' from '10'. */ #define WORLD 10 ``` > > https://github.com/goldsteinn/assembly-beautifier Thats not an official tool. Its code quality is not really up to standard and I can't really commit to maintaining it. If its improved to a state where its good enough for GLIBC I'll post a patch. > > Thank, > Sunil > > On Thu, Feb 3, 2022 at 2:00 PM Noah Goldstein via Libc-alpha > <libc-alpha@sourceware.org> wrote: > > > > Reformats to match style of other hand coded assembly files. > > > > The changes are: > > 1.

V2 (note gmail is eating the tabs, but the examples where I mention them will have them when posted on the wiki). == x86 GAS (Assembly) == The following are stylistic conventions for x86 GAS contributions. Other style conventions that are relevant to x86 GAS syntax are also included (for example [[https://sourceware.org/glibc/wiki/Style_and_Conventions#A79-Column_Lines|Column Limit of 79]] and [[https://sourceware.org/glibc/wiki/Style_and_Conventions#Nested_C_Preprocessor_Directives|Nested Preprocessor Directives]] 1. Instructions should be proceeded by a tab. 2. Instruction less than 8 characters in length should have a tab between it and the first operand. 3. Instruction greater than 7 characters in length should have a space between it and the first operand. 4. There should be a space after the comma seperating operands. For example for rules 1, 2, 3, and 4: ``` /* <tab><short instruction><tab><op0><comma><space><op1>. */ addl $1, %eax /* <tab><long instruction><space><op0><comma><space><op1>. */ vpmovmaskb %ymm0, %eax ``` 5. Comments should be indented with code: For example for rule 5: ``` /* Function XYZ returns. */ ENTRY(XYZ) /* Return from XYZ. */ ret END(XYZ) ``` 6. Tab after `#define`d names and their value. For example: ``` /* No value for 'HELLO' so no tab afterwards. */ #define HELLO /* Value for 'WORLD' so tab separated 'WORLD' from '10'. */ #define WORLD 10 ``` 7. Use C-Style comments. 8. Comments should be filled to obey the 79 character column limit. For example: ``` /* Bad: This comment is going to go beyond the 79 character column limit but be on one line. */ /* Good: This comment is going to go beyond the 79 character column limit but be on one line. */ ``` > > Thank you so much. > Sunil > > On Fri, Feb 4, 2022 at 11:46 PM Noah Goldstein <goldstein.w.n@gmail.com> wrote: > > > > On Sat, Feb 5, 2022 at 2:01 AM Sunil Pandey <skpgkp2@gmail.com> wrote: > > > > > > Hi Noah, > > > > > > Since this patch is about glibc assembly language formatting, it may be > > > helpful to everyone, if there is a section for glibc assembly coding > > > in manual. > > > > > > https://sourceware.org/glibc/wiki/Style_and_Conventions > > > > > > You may also consider putting your tool in glibc code base, so that people > > > can easily find/use it to check/format their assembly code. > > > > Like the idea.
