[ELF] Move markUsedLocalSymbols from Writer to markLive. NFC (#209035)
markUsedLocalSymbols (https://reviews.llvm.org/D77807) sets the USED
flag on local symbols referenced by relocations so that -r/--emit-relocs
with --discard-{locals,all} preserves them in the symbol table.
Move the scan into markLive's !gcSections branch to be closer to
MarkLive::resolveReloc. The scan now iterates sections via relsOrRelas,
handling CREL uniformly, and runs in parallel.
This is a step toward fixing #160789
[SLP] Don't truncate compare constants that change value at the demoted width
SLP preserves the original bit width when narrowing compare operands,
but doesn't always account for the required size convertion in LLVM IR.
This can produce incorrect compare constants after truncation.
Fix this by using getSignificantBits() for sign-extended operands,
forbidding truncation for signed predicates on zero-extended operands,
and checking the correct operand in the LBW > RBW case.
www/{pecl|php}-http: Convert port
ext-http extension aims to provide a convenient and powerful set of
functionality for one of PHPs major applications. It eases handling of
HTTP URLs, dates, redirects, headers and messages, provides means for
negotiation of clients preferred language and charset, as well as a
convenient way to send any arbitrary data with caching and resuming
capabilities. It provides powerful request functionality too.
Please note that pecl infrastructure is being deprecated so create a
different port which is not dependent on pecl infrastructure.
This commit also removes pecl-http ports in lieu of this port.
