treewide: replace verbose copyright headers with SPDX tags SPDX is an international standard for documenting software license requirements. Remove the existing headers and replace with a brief SPDX preamble. See: https://spdx.dev/use/specifications/ The script used to convert the files is added to "tools", and the file header templates in headers/ are updated. Signed-off-by: H.

Add copyright headers to the .c/.h files in the main directory Add copyright headers to the .c/.h files in the main directory. For files where I'm sure enough that we have all the approvals, I have given them the 2-BSD license, the others have been given the "LGPL for now" license header. Most of them can probably be changed after auditing. Signed-off-by: H. Peter Anvin <hpa@zytor.com> 2009-06-28 17:13:04 -07:00
stdscan: abstract out the saving/restoring of parser state The parser state does not just necessarily include the position of the buffer, but make it possible to maintain additional state. Furthermore, add an explicit ability to push back a token. All of this might make it easier at some point in the future to keep track of horizontal position, although that will require lots of changes to the preprocessor. Signed-off-by: H.

Finishing touches on perfect hash tokenizer; actually turn the thing on Finish the perfect hash tokenizer, and actually enable it. Move stdscan() et al to a separate file, since it's not needed in any of the clients of nasmlib other than nasm itself. Run make alldeps. 2007-08-30 22:35:34 +00:00			`*/`

stdscan: switch to stdscan_get/set routines Instead of manipulating stdscan buffer pointer directly we switch to a routine interface. This allow us to unify stdscan access: ie caller should "talk" to stdscan via stdscan_get/set routines. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> 2009-10-29 23:09:18 +03:00
