Actualmente, el c\u00f3digo agregado al n\u00facleo debe cumplir con la especificaci\u00f3n ANSI C (C89), que fue formulada en 1989.     <\/p>\n<p>El problema relacionado con Spectre en el c\u00f3digo fue causado por la continuaci\u00f3n del uso de un iterador definido por separado despu\u00e9s del bucle; se utiliza un macro para recorrer los elementos de la lista enlazada y, dado que el iterador del bucle se pasa a este macro, se define fuera del propio bucle y permanece accesible despu\u00e9s del bucle. El uso del est\u00e1ndar C99 permitir\u00eda definir variables para el bucle en el bloque for(), lo que resolver\u00eda el problema sin necesidad de soluciones alternativas.      <\/p>\n<p>Linus Torvalds estuvo de acuerdo con la idea de implementar el soporte para especificaciones m\u00e1s nuevas y propuso que en el n\u00facleo 5.18 se utilizara el est\u00e1ndar C11, publicado en 2011. Durante la compilaci\u00f3n preliminar, no se encontraron desacuerdos en GCC y Clang en el nuevo modo. Si no surgen problemas imprevistos durante las pruebas m\u00e1s exhaustivas, en los scripts de compilaci\u00f3n del n\u00facleo 5.18 la opci\u00f3n \u2018\u2014std=gnu89\u2019 ser\u00e1 reemplazada por \u2018\u2014std=gnu11 -Wno-shift-negative-value\u2019. Tambi\u00e9n se consider\u00f3 el uso del est\u00e1ndar C17, pero en ese caso ser\u00eda necesario aumentar la versi\u00f3n m\u00ednima de GCC. La inclusi\u00f3n del soporte para C11 se ajusta a los requisitos actuales para la versi\u00f3n de GCC (5.1).<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
