How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-c
aais actually a pair of functions rather than plain integers.xx()function lets you redefineauto0()andauto1()to makeslow()faster thanfast().xx()still contains a pointer toint aa[2]but in my real code I need to callaa0()andaa1()for each access.int bb[2]is really an array, but I don't see how to choose between e.g.aa0()andbb[0]using your approach. Am I missing something?auto0()is like{ return mode ? aa0() : bb[0]; }. And similar forauto1(). This complicates the example somewhat, but GCC makes the same "mistake" in optimizing, with an extra instruction and an extra register used inslow().
