Non-comprehensive list of changes in this release¶
ELF Improvements¶
-z nosectionheaderhas been implemented to omit the section header table. The operation is similar tollvm-objcopy --strip-sections. (#101286)Section
CLASSlinker script syntax binds input sections to named classes, which are referenced later one or more times. This provides access to the automatic spilling mechanism of –enable-non-contiguous-regions without globally changing the semantics of section matching. It also independently increases the expressive power of linker scripts. (#95323)
Breaking changes¶
COFF Improvements¶
/includeglobhas been implemented to match the behavior of--undefined-globavailable for ELF.
MinGW Improvements¶
--undefined-globis now supported by translating into the/includeglobflag.
